This adds a basic WebStorm project for devs that want to use WebStorm.
It's not as robust as the Eclipse set up yet, but I'll remedy that in a
future PR. For now:
1. Configure code formatters to mimic Eclipse formatting. It's not 100%
but it's close
2. Add a File Watch that triggers `ant build` whenever a glsl file is
modified.
3. Mark `Build` directory as ignored, the root directory as resource root,
and the `Specs` directory as test root.
