Update .gitignore and fixed rts plugin classpath

* We ignore generated files and folders:
  - bin
  - target
  - xtend-gen
  - ._trace
  - xtumlrt.*/src
  - .gitignore (we have only one global gitignore)
* The classpath for org.eclipse.papyrusrt.rts included the missing (and
unnecessary) src folder. We removed this entry.
