Code and directory structure

[gausie]

Questions to answer:

• We can't keep putting classes in libkol/... can we? Where do they go that would be familiar to a normal python developer
• How do we want to support content-based functionality? My current thoughts are a content directory, and you could do something like from libkol.content import KremlinsGreatestBriefcase or something to start using that
• Is passing the session around like this good? At the moment we aren't really getting the benefit of either approach because we use a singleton for the Models but pass it around everywhere else. Passing it around is great for the possibility of running multiple concurrent bots from a single script, which wouldn't really be possible. Singleton is good for ease of use.
