Allow to save user files to dropbox or as a gist

It would be awesome if the various user settings files could be stored as gist on github. That's what I'm doing now (keeping a copy of those files on github), but it would be awesome if I didn't have to periodically apply them to all my machines.

It could be done for example by putting a file in ~/.sublimetext on Unix systems (and a similar place on Windows) for example. For github, user's API token (or whatever's needed) could be stored there and ST2 would go then ahead and read/save files from gist.github.com instead of the local FS.

Those who'd like to use this would then only need to copy that one file to their machines and get the benefit of having shared settings.
