Add --bbox filtering to osm import-history
fetch changesets in batches of 100
Fix bug that prevents init to configure the backend stores.

The default backend config is being set after the effective config builder map
is populated with the provided config options, hence overriding them, instead
of the other way around.
Fix config set up of BDBJE staging database.

The setting for the JE staging db that makes it use the
non transactional je.properties got lost. Restore it.
Replaced osm point cache by a better implementation and improved RevTreeBuilder2's NodeIndex.

The current osm point cache performance declined severely as the number of coordinates
increse, since the temporary bdb je database competes with the staging and object db's
for heap memory on the shared bdbje cache.

It is now replaced by MappedPointCache which is a PointCache that uses a memory mapped
file to store the coordinates in sorted chunks, and hence doing most of the work in
off-heap memory, several times faster than the bdb je implementation. It also stores
ordinates as ints following OSM's to/from decimal conversion rules.

The current RevTreeBuilder2 NodeIndex lead to high memory usage and could also be improved.
It is now improved and its interface extracted to allow for alternate implementations.

Fixed some issues with the authors in the statistics web op.
Reverted gzip compression for some remote requests.

The compression was causing an issue in some cases such as
cloning from the mac command line, or geoserver to geoserver
repo communication.  Commenting it out so that geogit remains
functional in those cases.
Make HttpRemoteRepo.pushNewData use the same logic than LocalRemoteRepo to set the remote ref name to be updated
remove GPL mention for the geoserver plugin as its not part of this codebase anymore
