optimizer should use apiContext, apiName, defineContext, and defineName

[unscriptable]

When compiling resources/modules, the optimizer should use apiContext, apiName, defineContext, and defineName to correctly generate the compiled code. Since plugins just blindly write out "define(" in their write methods, the build tool has to compensate for this by scanning and correcting the build output.

Calls to curl( should also be converted (but not calls to require(!).

This issue is related to cujojs/curl#70 since we will eventually use cram.js to build the dist versions of curl.js. cc @papirosko
