A couple of documentation improvements

- Add some missing to the turtle API docs
 - Version history for peripheral and redstone. I /think/ this is
   complete.

+### Documentation
+When writing documentation for [CC: Tweaked's documentation website][docs], it may be useful to build the documentation
+and preview it yourself before submitting a PR.
+
+Building all documentation is, sadly, a multi-stage process (though this is largely hidden by Gradle). First we need to
+convert Java doc-comments into Lua ones, we also generate some Javascript to embed. All of this is then finally fed into
+illuaminate, which spits out our HTML.
+
+#### Setting up the tooling
+For various reasons, getting the environment set up to build documentation can be pretty complex. I'd quite like to
+automate this via Docker and/or nix in the future, but this needs to be done manually for now.
+
+This tooling is only needed if you need to build the whole website. If you just want to generate the Lua stubs, you can
+skp this section.
+ - Install Node/npm and install our Node packages with `npm ci`.
+ - Install [illuaminate][illuaminate-usage] as described above.
+
+#### Building documentation
+Gradle should be your entrypoint to building most documentation. There's two tasks which are of interest:
+
+ - `./gradlew luaJavadoc` - Generate documentation stubs for Java methods.
+ - `./gradlew docWebsite` - Generate the whole website (including Javascript pages). The resulting HTML is stored at
+   `./build/docs/lua/`.
+
+#### Writing documentation
+illuaminate's documentation system is not currently documented (somewhat ironic), but is _largely_ the same as
+[ldoc][ldoc]. Documentation comments are written in Markdown,
+
+Our markdown engine does _not_ support GitHub flavoured markdown, and so does not support all the features one might
+expect (such as tables). It is very much recommended that you build and preview the docs locally first.
+
+### Testing
+Thankfully running tests is much simpler than running the documentation generator! `./gradlew check` will run the
+entire test suite (and some additional bits of verification).
+
+Before we get into writing tests, it's worth mentioning the various test suites that CC: Tweaked has:
+ - "Core" Java (`./src/test/java`): These test core bits of the mod which don't require any Minecraft interaction.
+   This includes the `@LuaFunction` system, file system code, etc...
+
+   These tests are run by `./gradlew test`.
+
+ - CraftOS (`./src/test/resources/test-rom/`): These tests are written in Lua, and ensure the Lua environment, libraries
+   and programs work as expected. These are (generally) written to be able to be run on emulators too, to provide some
+   sort of compliance test.
+
+   These tests are run by the '"Core" Java' test suite, and so are also run with `./gradlew test`.
+
+ - In-game (`./src/test/java/dan200/computercraft/ingame/`): These tests are run on an actual Minecraft server, using
+   [the same system Mojang do][mc-test]. The aim of these is to test in-game behaviour of blocks and peripherals.
+
+   These are run by `./gradlew testInGame`.
+
+## CraftOS tests
+CraftOS's tests are written using a test system called "mcfly", heavily inspired by [busted] (and thus RSpec). Groups of
+tests go inside `describe` blocks, and a single test goes inside `it`.
+
+Assertions are generally written using `expect` (inspired by Hamcrest and the like). For instance, `expect(foo):eq("bar")`
+asserts that your variable `foo` is equal to the expected value `"bar"`.

+ * A generic source of {@link LuaMethod} functions.
+ *
+ * Unlike normal objects ({@link IDynamicLuaObject} or {@link IPeripheral}), methods do not target this object but
+ * instead are defined as {@code static} and accept their target as the first parameter. This allows you to inject
+ * methods onto objects you do not own, as well as declaring methods for a specific "trait" (for instance, a
+ * {@link Capability}).
+ *
+ * Currently the "generic peripheral" system is incompatible with normal peripherals. Normal {@link IPeripheralProvider}
+ * or {@link IPeripheral} implementations take priority. Tile entities which use this system are given a peripheral name
+ * determined by their id, rather than any peripheral provider. This will hopefully change in the future, once a suitable
+ * design has been established.
+ *
+ * For example, the main CC: Tweaked mod defines a generic source for inventories, which works on {@link IItemHandler}s:
+ *
+ * <pre>{@code
+ * public class InventoryMethods implements GenericSource {
+ *     \@LuaFunction( mainThread = true )
+ *     public static int size(IItemHandler inventory) {
+ *         return inventory.getSlots();

+ *
+ * @see ComputerCraftAPI#registerGenericSource(GenericSource)
