added limit(x,y) for paging. broke apart QueryTestSuite into GraphTestSuite and VertexTestSuite.
Merge branch 'queryfeature' of git://github.com/tinkerpop/blueprints into queryfeature
limit(x,y) is now skip(x).limit(y).
more work on default query.

OrientDB: supported min/max in queries
merged master and static String Lucas latest SKIP LIMIT work.
first big push on #313 -- also includes has(key) and hasNot(key).
Add missing graph.shutdown() in txn graph test

The method testVertexPropertiesOnPreTransactionCommit() in
TransactionalGraphTestSuite generated a test graph but did not call
shutdown() on it.  I think omitting shutdown() is an error, but I
could be mistaken.  Every other method in the file that generates a
graph appears to call shutdown().  If this method really isn't
supposed to call shutdown(), then a comment noting it might be helpful
to future readers.

I found this when trying to upgrade Titan from Tinkerpop Stack 2.3.0
to 2.4.0-SNAPSHOT.  Omitting shutdown() caused errors during test
cleanup using a BDB TransactionalGraph implementation in Titan.
OrientDB query: supported multiple items in OR
removed ordering assumption.
Merge pull request #402 from dalaro/master

Add graph.shutdown() call in a TransactionalGraph test method
test cases around ORing of Comparables.
Merge branch 'master' into queryfeature
OrientDB query: supported OR with any operators
removed var args on the has(key,compare...) per Daniels nice thoughts.
has(key) is now simply has(key,values...) but key existence. likewise for hasNot().
