Experimental Titan on TinkerPop 2.5.0-SNAPSHOT
New exclusions for changes in snapshot dependencies
Bumped to TinkerPop 2.5.0
Brought up to date with titan05
Merge branch 'titan05' into tp-2.5.0-SNAPSHOT
Removing anachronistic titan-dist-* poms

These crept back into the experimental TP 2.5.0 branch based on
titan05 for some reason
BerkeleyJEBlueprintsTest fixes

Modified cleanUp(), pre-suite, and post-suite methods to detect and
warn on graph leaks in the underlying Blueprints test methods.  Also
made cleanUp() and the post-suite method stop leaking unclosed store
managers and made cleanUp() stop behaving like a no-op for the first
test in the suite (important for repeated runs without a `mvn clean`
in between).
Merge branch 'titan05' into tp-2.5.0-SNAPSHOT
Throwing exception when attempting to remove an already removed element
No exception when removing edges, only vertices. Fixed lacking it() referentiality in StandardVertex.remove()
Keep all modified vertices in cache, not just those with added relations, so that we can keep track of vertex lifecycle states.
