list index out of range when editing

[David Caro]

When running clicompanion, if you edit the last command, and then move the command somewhere else on the list, if you click edit again (without selecting another command) you get a list index out of range error, just because you are not selecting any rows.

$ clicompanion
using locale in system
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/clicompanionlib/controller.py", line 185, in edit_command
    row_int_x = int(view.ROW[0][0])
IndexError: list index out of range

Patch appended, just added a simple if to assure that the view.ROW object is not null (or empty in this case).

Patch checked and have my recommendation.

Ready to merge to trunk.

Thanks!
