Icinga Director v1.10.1

This is a minor bugfix release, addressing issues with modifying services via
the monitoring module, Sync problems and a copy and paste error in the DB schema,
which caused problems for fresh installations since v1.10.

Please note that a long-standing issue for our Sync Rules has been fixed: with
"merge" policy, NULL properties have been ignored for quite some time. This has
now been fixed. If in doubt, please preview your Sync Rules to make sure,
that they behave as expected.

This release brings a small schema migration, cleaning up invalid Sync history
entries. If in doubt, please create a database backup first.
