Made `express` a soft (runtime) dependency.

Update coffeescript helpers' based off CS 1.8.0 source.
Removed databag
Fixes for JSON/JSONp tests.
codename is gone
Clarify version.
Version is not latest (we'll keep 0.5 as latest for now).
partials: gone since Express 3
removed the adapter code
zappa_fs: ugly, gone
Removed references to coffeecup, connect.
Express is no longer built on connect.
Only one option for `io`.
If set to false, disables io. Otherwise might reference a socket.io module. Or leave undefined to use the default.
no more zappa_fs root, no more adapter
Initial attempt at replacing zappa_fs with custom `view`-handling code.
