Deno's node emulation can run TiddlyWiki now that it supports the VM isolates API, but the window global exists in that environment, so both browser and node were being detected, causing the autoboot to trip up on nonexistent argv, as the boot was happening in the constructor right before argv was set.

moduleType: type of module

definition: object, function or string defining the module; see below

exports: exports of the module, filled in after execution
|

The `definition` can be of several types:
|
|
|
|
* An object can be used to directly specify the exports of the module
|
|
* A function with the arguments `module,require,exports` that returns `exports`
|
|
* A string function body with the same arguments
|

Each moduleInfo object is stored in two hashmaps: $tw.modules.titles and $tw.modules.types. The first is indexed by title and the second is indexed by type and then title
