Created a new file for convenience/utility macros.
Documentation fixes.
Small update to the Macro's header.  Also added it in Mezzanine.h.
Updated a couple enums in enumerations.h so they use the new BitMask macro.  Also added an enum for pausing of world managers.
Fixed warnings.
More documentation fixes.  We had a lot of places still referring to the entresol as if it were still called "World".
Fixed some warnings.
Tiny doc fix.
Added another typedef to make working with NameValuePairLists a bit easier.
Renamed the XML property from "MaxObjects" to "MaxProxies" as that is more accurate to future changes.
A number of improvements and ground work done on the World and WorldManager classes.
