Improve nicklist and hash coloring
Set short name
remove mention color. Script colorize_nicks.py does this for every
buffer
Remove support for static nick color. Timeline should looke like a
regular weechat channel and use same coloring. Also remove @ in start of
every name, it's just visual noise.
More acknowledgements.
Get all followed.

Turns out that twitter limits the amount of followed with one request to 20, so
the plugin only showed 20 of the people you followed. This uses the Cursor
class to get them all. This will make the plugin load a bit slower.
Version bump.
