Ad-hoc network support is added ("O").

This commit is should be the last one containing new interface elements. :-D
This also may not work directly from the install.  I need to change some stuff
first.
curses/curses_misc.py:
  Fixed bug in Dialog2 where mouse clicks would cause the program to crash
  Added DynEdit and DynIntEdit, Simple DynWrapped widgets, nothing special
    about them
curses/wicd-curses.py:
  Added support for Ad-Hoc network controls (I don't know exactly how this
    works)
