Static analysis

[chenglou]

Throwing this out here for discussion.

RCSS is an experiment (one that seems to work fine on a small scale at least). There are already plenty of other asset bundling/loading solutions that use static analysis. Currently I have no plan in introducing some here, partially because I want less overlap and partially because it gets harder to maintain and is one extra compilation step.

I'll see how far I can piggy ride on whatever existing require solution (browserify, webpack). Maybe I'll consider static analysis in the future.
