Make function comments available to ZeroBrane Studio

[mikaelkindborg]

Problem:

The Lua IDE ZeroBrane Studio (http://studio.zerobrane.com/) needs input data for code completion and documentation comments. Today this is not available in one place.

The file maapi.idl contains function comments (with doxygen comments) for ma* functions that can be written to the output file generated by the part of the moSync IDL-compiled that produces the header file for the tolua binding generator.

By combining this output with the header files for Sys* functions in LuaLib we can get one file that contains documenation comments and functions declarations for all ma* and Sys* functions in MobileLua.
