Fix small errors and typos across the board

Fixed the things that my linter (pyflakes 0.7.3) picked up,
with the exception of the following:

./modules/rfc/cmd_list.py:27: undefined name 'channelNames'
./modules/rfc/cmd_list.py:28: undefined name 'channelNames'

These will need to be looked at by someone who knows what the code
is actually meant to do.
Add self to contributors list
stripcolors: module to disallow voiced and lower from sending format chars
customprefix: Fix newline at the end of the file
misc changes to logic that hopefully make it more readable
Merge pull request #6 from Heufneutje/formatting

customprefix: Fix newline at the end of the file
Merge pull request #4 from ekimekim/dev/0.3

linter fixes, add self to contributors, stripcolors
A couple things for consistency
Merge pull request #8 from ekimekim/style

misc changes to logic that hopefully make it more readable
Allow metadata to come from specific servers
Merge branch 'dev/0.3' of github.com:ElementalAlchemist/txircd into dev/0.3
Add a way to just add list modes to users/channels (for server burst only)
Make ircd.storage keep a cache and write back every 5 sec

This prevents performance problems due to pickling and unpickling a thing thousands of times
