20474dabac relay: fix many bugs with nick collision handling, and add flood prevention for fixing nicks 
Closes #85. Nick collisions caused by internal clients are handled fine now, including the following cases:
- Abusing spawnClient to create a user with the same nick as a relay client, but with a lower TS.
- When both an UID (e.g. 42XAAAAAA) and a tagged UID (_42XAAAAAA) exist on the same network (the two will both try to take the same nick of _42XAAAAAA/net over the relay).

The case where changing NICK from a long cut-off nick to another long cut-off nick is also mitigated. somelongnick/net won't show nick changes to somelongnic//net if the old and new nicks have give the same normalized relay nick.

This introduces a new dependency, expiringdict, from https://pypi.python.org/pypi/expiringdict/1.1.2, which is used as a cache for flood prevention.

821f546f12 Make sure the PyLink client rejoins all relay channels on KILL 
This adds a new internal hook, 'PYLINK_SPAWNMAIN', which is triggered whenever Irc().spawnMain() is called.

6ebe6e7867 relay: check for whether clients are relay clients, instead of just internal clients

4382b22138 relay: warn users when messaging channels they aren't in / remote users w/o sharing a channel 
Some refactoring of relay's PRIVMSG handling is done here:
- Messages to channels the sender isn't in are dropped, with a notice warning sent.
- Messaging a remote user without sharing a channel with them raises an error, and is dropped.

Closes #91.

e354ada838 relay: fix nick collision loop on SAVE + when both tagged UID and untagged UID exist on one net 
This fixes a clash when for example: both 42XAAAAAA and _42XAAAAAA exist on a network, and PyLink tries to relay both nicks as _42XAAAAAA/network.

Also, this adds an oldnick argument to the SAVE protocol handler, which is then used by relay.normalizeNick to check whether the original pre-SAVE nick is also in use, in the event of nick collisions.
