Updates the README.
Removes _logWrite.

This method was part of the old logging functionality. I forgot to
remove it when I changed that.
Removes squery and summon.

These methods were bascially just there for completeness sake and
weren't actually implemented. Both cover functionality which is either
not implemented by most IRCds or basically useless today.
Adds @staticmethod to two methods.

_addHashes (Core) and _parseParams (Parser) don't make much sense
outside of their respective classes, so it's better to have them as
static methods instead of module-level functions.

Also adds a NOTE to the unused IRCError import in blackbox.py, which is
there so that it can be accessed by users of the module.
Fixed blackbox.Oper's init method.
Adds nickname storage + getter.
Adds optional passwords to die() and rehash().
Completes the module docstring for blackbox.py

For some deeply mysterious reason surely not related to the absentmindedness of
the developer, the docstring ended mid-sentence. Investigations are underway
but unlikely to produce results.
Removes a lot of unnecessary if/else crap (<3 Ferus)
It was RESTART, not REHASH, that required a pass.
Fixes restart and rehash. Again.

Forgot to remove the password argument from rehash and forgot to add it
to restart.
Corrects docstring of close().
Version 0.7 release (this pleases the Ferus)
Merge branch 'release-0.7'
