.cheat directories should be searched for recursively

[kapad]

Is your feature request related to a problem? Please describe.
Cheat only searches the current directory for a .cheat directory.

Describe the solution you'd like
cheat should search the directory hierarchy for .cheat directories. This scope could be limited to say, search the directory hierarchy until $HOME and no further.

Describe alternatives you've considered
I've found cheat useful in project directories, but documentation of this sort works only if I am in the root of my project. I would like this to work even if I am in a sub directory without having to cd to my project root.

Hi, @kapad

Yeah, I've been annoyed by this behavior myself. I'm in favor of changing it.

In the near-term I'll be refactoring how cheat loads cheatsheets while addressing some tangentially-related tickets. I'll tackle this at the same time.
