gmail: reworked feed handling and changed username format

Nothing hard coded in the worker now. Feeds are together with user
data, easily swaped. Feeds are not widget args because user needs to
modify the file for login data anyway. No progress toward safer
storage, Kwallet looks promising but dbus handling is hell - what of
non KDE users? Every other script, including much praised checkgmail
has plain text login. Nobody cares?
