Remove function prefixes

[lassade]

It is common practice in C and C++ to add function prefixes like: glBindProgram or b2World or rcIgnoreUnused we should have a option to remove these.

the expected outputs shuold be: glBindProgram -> bindProgram b2World -> World (in case it's a class or struct the first letter should be in upper case) rcIgnoreUnused -> ignoreUnused
