• avoid static construction (and global variable access) in a smarter, more portable way, to later enable MUTLI_THREAD mode to work on other platforms and compilers.

• kjs/CommonIdentifiers.cpp: Added. New class to hold all the shared identifiers. (KJS::CommonIdentifiers::CommonIdentifiers): (KJS::CommonIdentifiers::shared):
• kjs/CommonIdentifiers.h: Added.

• kjs/ExecState.h: (KJS::ExecState::propertyNames): Hand the CommonIdentifiers instance here for easy access. (KJS::ExecState::ExecState):
