copy additional resources, parse file globs

[agallant]

Fix #3 - also enables file glob patterns for all options. This tool is now fairly functional, though loading resources within a Firefox addon is somewhat inevitably clunky. Specific caveats:

• ugly hash-y path (the self sdk cannot be accessed in all scopes, so the path sometimes needs to be hardcoded)
• .jsm modules can be loaded with Components.utils.import but other things (e.g. .json, .js) don't have a consistent way to be pulled in

On the plus side, freedom.js does work just fine when pointed at a .json file (loads it and runs whatever module it has with it), so I think it will suffice for our tests.

I'm going to go ahead and merge this in the name of cutting an improved release, but am still very open to review/feedback as desired.
