[Patch] allowing to optionally not link certain modules directly

Maven-Idea currently allows to centrally switch linking modules on or off (using the switch link-modules). This patch allows to specify exactly which modules will not be linked directly. For our project (Apache MyFaces, to be more precise) this is essential - we need to link some modules as a jar (cause there are some artifacts in these modules which need to be built specifically), but don't want to loose the freedom of working with the other modules without having to go through a full maven build always.

This patch adds a new property:

linkModulesExcept

which is treated as a comma-separated list of modules which will necessarily be linked as a jar.

P.S.: for people trying this out locally - I had to change the version in the pom of the maven-idea-plugin from 2-SNAPSHOT to 2 for building the maven-idea-plugin locally.
