FactWrapper

Known Bugs;
+ Saving/Loading [Experimental]

BugFixes;
+ Server caching may pose the need for postponed Stage loading
+ Server cheches wrong label -> send fact with new one.
+ New Facts may have Definisions()==null -> null.ToString() for ID
+-> MMTFact.ToString() as Fallback

Facts;
+ Further decoupled from FactRecorder
+-> labeling done JIT by FactRecorder
+ Caching: object CompiledValue && Expression CompileBase

Misc;
+ added SOMDoc(from)Object(object)
+ StageStatic.ShallowLoadStages(bool): streamlined loading in case of failure due to unloaded dependecies (e.g.: ContextRecorder)
