Bot.py "home" path is relative to where the script is executed.

[Walker]

I noticed that when executing the ./jenni script from outside the jenni directory (say, root), modules were not loading and the python broke on an empty sequence (empty list of modules).

~ $ ./jenni/jenni 
Warning: Couldn't find any modules

Currently, bot.py only recognizes modules if ./jenni is run from within the top level directory. This is, I believe, due to the way the home directory is being calculated. Currently:

# getcwd() is relative to your location in the file tree.
home = os.getcwd()

I believe it would be better calculated using the files realpath. This way, the initial script can run from any directory.

# realpath is the absolute path of the file.
home = os.path.dirname(os.path.realpath(__file__))
