* lib/screenshooter-actions.c: fix Open with mode.

  * lib/screenshooter-dialogs.c:
    - Start to rewrite the dialog code on the basis of a patch by David
      Collins.
    - Remove frames.
    - Add alignments.
    - Add copy to clipboard function.
    - The layout still needs to be tweaked.
    - The dialog for the plugin crashes at the moment, I'll fix this
      later.
