Fixed multiple iteration against linked properties
Supported registration of storages by path when multiple Orient instances run on the same JVM
Refactored server and disributed layer to support multiple OServer instances on top of the same JVM. This is needed for tests against distributed servers
Minor: removed edge label
Supported "plocal" as database type in studio

Fixed bug on auto parsing date from JSON: the database configured format was't used and both DATE and DATETIME used the dateformat of DATETIME.
Fixed problem on receiving a date from JSON. Now the new formatting parameter dateAsLong allows to export dates and datetimes properties as long. This speeds up database export/import and let to have the maximum precision even if the datetime settings aren't (like by default that ignore milliseconds)
Distributed: small refactoring to write distirbuted test just extending AbstractServerClusterTest
Distirbuted architecture: improved messages, minor fixes
Replication: fixed conflicts on record create. Improved and simplified the task management
Distributed: minor refactoring on method names
Distributed: new test cases with indexed massive insertion
Minor: check if serialization is null in transaction
Upgraded TinkerPop stack
