Add access transformer, update build to use it.

This probably won't run correctly because the AT isn't being applied at runtime yet.
Added IFMLLoadingPlugin instance, the mod now loads correctly.
Use ant filtering for MC version number.
Use package exclusion.
Add transformer to add methods to Container classes.
Add rowSize method generation for simple constant sizes.
Merge branch 'develop'
Disable version check.
Generate default inventory check based on current check in ModCompatiblity.
Hook up calling the generated methods.

Everything surprisingly works pretty well, other than no support for the mod compatibility layer yet.
Add a self-forwarding method generator (calls this.forwarded()).
Support for generating a static->instance forward via first argument.

Turns out it's basically equivalent to generating the self-forwards, except the method is marked static.
Make InvTweaksObfuscation helpers static, setup for replacing the slot map generation.
Implement slotmap tranforms.

Everything should work for the vanilla containers supported (except ContainerCreative) at this point.

API/ModCompat containers are not ported to the transformer yet.
Reformat code.
More reformats.
Merge pull request #49 from Kobata/coremod

Change to coremod, use transformers for mod-compatiblity
