Sync config file on save

[joelgriffith]

Since both the client and remote machines rely on a single config object, and we expose editing this config with sicksync -c, it'd be nice to have a "listen" on that save event and sync the config in a bi-directional fashion.

This likely won't need to be addressed as in v1.2.0 we're dumbing down remote machines to only apply changes from the client (and not look at configs in the remote repo).
