Made geogit CLI exit with non-zero exit code when a wrong command is entered
New --bounds option to the diff operation to print out the boudning box of a diff instead of the diff itself.

There's also a new plumbing DiffBounds command for the java API.
So far the command assumes all features are in the same CRS.

--bounds option to CLI's diff backed by a new DiffBounds plumbing command
extra precondition check for the tag command
Refactored the LowestCommonAncestor algorithm to the op.
Initial implementation of BDBJE graph database.
Other graph backends now run FindCommonAncestor tests.
Refactored the sparse path check out of the graph database.
Some JEGraphDatabase improvements.

- Use a single transaction in put(ObjectId commitId, ImmutableList<ObjectId> parentIds)
  to insert update the node and the parent nodes.
- Use a more compact serialization format than default java serialization, based on BDBJE TupleBinding
- Remove some dead code
- Use its own environment, and the raw byte[] object id as key instead of a string. It uses a
  separate database even if using the same environment than JEObjectDatabase so no need for the
  extra overhead.
Fixed an issue which caused clone to fail when tags were present.
