Threads that aren't daemon threads can keep the JVM from shutting down.
I'm certain that this doesn't happen very often but if one of these
threads hangs it can cause the rest of the JVM to not shut down
when the main thread exits.
By making all threads daemon threads if the main thread terminates
the rest of these threads will shut down.
Before we were setting the default as the previous value each time. Here
we store each property in a separate field, allowing us to access them
without setting a default.
If the path includes no wildcards then it just checks it exists.
If it does, instead of scanning the entire tree, it works out the last
directory before the wildcard and starts scanning from there.
Closes#89
We now listen to neighborChanged instead of onNeighborChange. This means
computers correctly detect redstone updates.
However, this leads to issues when moving turtles, so we defer the block
update until the turtle has finished moving.
Updated the source code to the version shipped as the 1.80pr0 alpha
release. Also removed some unnecessary files from the LuaJ subfolder
which were bulking up the repository.
