Commit 0c7a050c 0c7a050c96880b28bc1f35ed514c015bc043608c by Nicolas Perriault

PhantomJS 1.7 compatibility. 

WARNING: PhantomJS 1.7 ships with its own implementation of the module
pattern, which is incompatible with what CasperJS provided.

So the CasperJS' `modules` directory has been renamed to `node_modules`
to allow loading CasperJS built-in modules natively.

CasperJS remains compatible with PhantomJS 1.6 though.
