[minion-cvs] Tag refactoring; email robustness.



Update of /home/minion/cvsroot/src/minion/lib/mixminion
In directory moria.seul.org:/tmp/cvs-serv25421/lib/mixminion

Modified Files:
	BuildMessage.py Modules.py Packet.py PacketHandler.py 
	ServerMain.py benchmark.py test.py testSupport.py 
Log Message:
Tag refactoring; email robustness.

BuildMessage, Modules, Packet, PacketHandler, ServerMain, test, testSupport,
   benchmark:
    - Separate 'tag' and 'exitInfo' as much as possible
    - Require all exit messages to have a tag.
    - Insist that exit types be 0x0000 or >= 0x0100.

Packet, Modules, test:
    - Catch invalid email addresses.
