Exclude git and DS_Store when not in project root

Make git and DS_Store files excluded by default, even when they are not at the root of the project.
Github fs, new token store (for storing secret-ish credentials).
Better UI for Github
Moved the zedrem user key into the token store so it's not visible in
your user preferences.
Important:
* The "zedrem"/* preferences will now be ignored (you can remove it)
* A new user key will be generated, retrieve it with the
  "Configuration:Zedrem:Get User Key" command
* To change the zedrem server to connect to, override the "zedremServer"
  preference.
