[xdot] Document the keystrokes that are recognized

[GoogleCodeExporter]

What steps will reproduce the problem?
1. xdot --help
2. man xdot
3. http://code.google.com/p/jrfonseca/wiki/XDot
4. etc.

What is the expected output? What do you see instead?
The only shortcuts that are mentioned are in the wiki
(Ctrl-drag and Shift-drag). I had to look in the source code to find out how to 
use the program.

What version of the product are you using? On what operating system?
0.4 on Debian

Please provide any additional information below.
The manpage was written by the Debian maintainer, but could be pulled upstream.

xdot is a really nice utility, but it's a pity it's not better presented via 
documentation and releases.

+1 Probably worth adding menu with Help, About, etc.

I've been just too busy to afford spending too much time on xdot. And the 
little I do spend is for others' sake, as xdot.py does everything I need.

If you could provide a patch for 
https://code.google.com/p/jrfonseca/source/browse/XDot.wiki?repo=wiki with the 
documentation I'd commit it.

Short cuts are now listed on xdot.py --help, which is also included verbatim in 
the wiki.
