[BUG] Fixing command plugin calls
[FIX] Removed unuused variable
[FIX] Re-add SIGUSR1 blocknotify

This does not allow you to close the process via CTRL+C anymore. Need to
kill the process PID via kill -KILL <PID>. Might be fixed sometime in
the future.
[IMPROVEMENT] Adding more sample commands

* !norris to fetch random Chuck Norris joke
* !fortune to fetch a random fortune
* Updated !help
[IMPROVEMENT] Display command exceptions in logging
[FIX] Properly read multiline HTTP output
[IMPROVED] More data in status command
[IMRPOVED] Better log output on command class
Overhauled socket connection handling

* [IMPROVED] Use non-blocking sockets
* [IMPROVED] Moved generic calls into IRC Class
* [IMPROVED] Created settings module to translate config to settings
* [IMPROVED] Error handling via logging in main while loop

Known issue: If the socket dies, the bot will not be able to detect it
yet. I am unsure how this would walk using select.select().
