Separate the set of general projects from the Scala artifacts

This commit refactors the 2.11.x community file, by placing
into a common file all the projects that do not depend upon
the way in which the Scala artifacts and modules are generated.

By doing so, it becomes possible to test the same set of
projects using, for example, an optimized or non-optimized
compiler, or the GenBCode backend, or different Scala
options that should be used for all projects (to be specified
using using "vars.base").
Add community-2.11.x.sh: only this script will be called by Jenkins

By moving the dbuild version etc in this script, it becomes easier
to make changes without having to change the Jenkins configuration
every time.
Adding the community bootstrap file

The community bootstrap file performs a full bootstrap similar
to the traditional starr/locker/quick. Details to follow.
Bump scalacheck to 1.11.3
