Status report: Make the code more abstract

by ritze

What I've done this week:

  • Finish splitting the language-support-cpp-java plugin in an indentation-c-style plugin and a language-support-cpp-java plugin without the indentation part
  • Did the same with language-support-python plugin
  • Export the utils classes of the two language-support plugins to libanjuta/anjuta-utils to prevent code duplication
