Increase the project version to 1.1.0 as this is a new feature version.

As for all new feature versions, increase the libtool .so version.
Only increase the revision, as no API's were added or removed.
It may look like I've increased it by 2, but that's because v1.0.8 used
Makefiles and was at 1:8:0.
