[2.0.1] DefinitionCache related bug-fixes

- Fixed bug where manually modified definitions were not saved via cache (mostly harmless, except for the fact that it would be a little slower)
- Configuration objects with different serials do not clobber each others when revision numbers are unequal
. DefinitionCache keys reordered to reflect precedence: version number, hash, then revision number
