fix compile error with xcode on case-sensitive file system.
Fix typo in AUTHORS

Jianfeng Zhou (NetGragon) -> Jianfeng Zou (NetDragon)
Add missing ccGLServerState to CCNode.pkg.

Without this missing enum the resuling cpp file would generate
an unused function warning.

Also, remove the duplication between build_macosx.xml and build.xml.
They only differed in single property.  Instead use build.sh, which
should work on all UNIXs, no just maxosx.
Add new port: Native Client
add setVisible() to CCEditBox [ios & mac]
add setVisible() to CCEditBox [Android]
add setVisible() to CCEditBox [Win32]
