Removed superfluous dependency to concrete Jangaroo compiler JAR.

Fixed that generated AS files were not picked up by AS->JS compiler.
Seems although we already tell the IDEA build process that we just
generated a source file, it also has to be marked dirty explicitly to
trigger the next compiler.
Also simplified filesToBeCompiled data structure: all dirty files from
the current moduleBuildTarget must be from the same module, and
the forTests flag also must be the same for one moduleBuildTarget.

Amend: Removed superfluous dependency to concrete Jangaroo compiler JAR also in IML.
Changed Jangaroo facet importer strategy to tweak WAR artifacts:
Instead of throwing away WEB-INF/lib references to Jangaroo modules and
reconstructing Jangaroo Packaging Output elements from module dependencies,
simply convert the WEB-INF/lib dependencies to Jangaroo Packaging Output elements.

Make JangarooPackagingOutputElement work in JPS build!
All we need is a custom PackagingElementSerializer that takes
care of deserializing JangarooPackagingOutputElements into
JpsModuleOutputPackagingElements using the relative output
path META-INF/resources.
Now, the whole Jangaroo build process should work in IDEA 13 with JPS.
More elegant solution to cast the compiler class that has been
instantiated via reflection into the desired interface.

Also mark dirty ActionScript classes generated from properties files.
clean-up

Make plugin deployment packaging work.
The compilers' 3rd-party libraries are now, like the compiler
 JARs, loaded from the local Maven repository. This shrinks
 the Jangaroo IDEA Plugin a lot and should make the plugin
 build portable. Be sure to execute mvn compile in the
 jangaroo-api module once to download the Jangaroo API
 1.0.x JARs to your local Maven repository, then you should
 be able to produce a Jangaroo IDEA Plugin zip as usual.
