Provide data api for getting shared data, locks, and game data

[Sheep-y]

Example:

api( "data sheepy.config" ); // Get a shared data
api( "data sheepy.config", ModConfig ); // Set a shared data

api( "data lock", "harmony" ); // Get "harmony" lock
api( "data rlock", "harmony" ); // Get "harmony" read lock, disposable style
api( "data wlock", "harmony" ); // Get "harmony" write lock, disposable style

// api( "data def PhoenixFacilityDef", "08a852ce-a6b6-3d84-cae6-302032199fca" ); // Access Lift Facility

data def is implemented by Scripting Library through pp.def and pp.defs.

It seems that Modnix will need a mod event api sooner than data or lock.

The lack of events is causing mods to be unable to listen for mod disarm, for example to disable console commands or reset javascript context. Its lack is also prevents Scriping Library from allowing other mods to share their helper objects.
