Update service initialization file

This will need to place a configuration file with:

* userid
* uuid
* password (optional)

Use it for even faster startup times, and running under the native
twisted reactor.

+TAC file for initialization of the imap service using twistd.
+
+Use this for debugging and testing the imap server using a native reactor.
+
+For now, and for debugging/testing purposes, you need
+to pass a config file with the following structure:
+
+[leap_mail]
+userid = "user@provider"
+uuid = "deadbeefdeadabad"
+passwd = "supersecret" # optional, will get prompted if not found.
