Fix username regex in cake plugin

[prplz]

On network I frequent, the ` character is common in nicknames and they deserve cake too!
Found the regex at http://stackoverflow.com/questions/5163255/regular-expression-to-match-irc-nickname .
The reason it has two groups of characters is that nicknames can't start with numbers.

I suggest this instead:

[a-z\d_\-\[\]^\\{}|`]{1,32}

Lets just go with checking for spaces, it doesn't really matter if it's a valid IRC nick. This is copied from how attacks.py validates.

And why do we need to block spaces again?

I know what this PR is about, was just asking a general question.
