MOVE is more efficient than COPY + DELETE, especially on COW file systems

- only 2 windows: main and error
- reworked configuration tab using GtkSwitch
- main tab includes the old "pause" control and the "log" dialog
  - log dialog automatically updated every 2 seconds
- status icon has no menu, it just pops up the window when activated
- missing configuration notification has now a button to pop up the
  configuration tab
- the "quit" control is in the gnome-shell top bar now

Thanks Kim Christensen for reporting this issue

Tests to fix http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685265

Now it is consistent. It use to be like:
  make test
  make test/suite
  make test T=suite/file

Avoid spawning a process every time a translation has to happen.
Also refactor some code, removing copy/paste
