http://bugs.debian.org/761524
[ Jakub Adam ]
* New upstream release (Closes: #761524).
* Refreshed d/patches.
* Don't build removed feature org.eclipse.linuxtools.tools.launch
  - merged into org.eclipse.linuxtools.profiling.
* Use javac target 1.7.
* Build new feature org.eclipse.linuxtools.dataviewers.feature
  - required by Valgrind integration.
* Build-depend on eclipse-remote-services-api and eclipse-cdt-autotools.
* Bump Standards-Version to 3.9.6.
* Override incompatible-java-bytecode-format - linuxtools needs Java 7.
* Remove unused codeless-jar override.

[ tony mancill ]
* Tweak short package description to make lintian happy.
