compare directories recursively

[basti1302]

Currently, passing two directories into icdiff gives

Traceback (most recent call last):
  File "/usr/local/bin/icdiff", line 536, in <module>
    start()
  File "/usr/local/bin/icdiff", line 519, in start
    lines_a = open(a, "U").readlines()
IOError: [Errno 21] Is a directory: 'server/'

Since it is advertised as a tool to compare two files, that is perfectly fine (except for that one could wish for a more user friendly error message) . However, it would be sooooo awesome, if icdiff would be able to compare full directory trees like diff with -r/--recursive.
