gmail: switch to ~/.netrc for login storage

Login information is now kept in the ~/.netrc file, which should be
readable only by the owner. This should solve futher problems with
unquoted characters addressed in the last commit. The format of the
~/.netrc file is as follows (also documented in the README):
machine mail.google.com login user password pass
