Merge pull request #62 from joelmccracken/master

I fixed the broken tests
Only load cache at projectile load time

Previously the cache file was loaded and evaluated everytime the major
mode was changed.  When using some other libraries, major modes change
a lot. For example, this mean that everytime I used `smex` or
`iswitchb-buffer`, I would have a long delay while the cache file was
loaded.

There's no real need to load each time a major mode changes, the only
regression would be a stale cache if the file was modified by a
separate process. I don't suspect anybody will hit that situation.
Create an empty hash-table for the cache if file doesn't exist
Use print0 for find in generic/SVN commands

A command's output is split by '\0' - this means the `find` command
needs the `-print0` flag to work properly.

first sketches of bookmarks feature
projectile-start-project lets any project be completed

I realized having the list be without started projects was actually
less useful to me, so disabling for now.
