aiaiai-sh-functions: remove [email] section from cfgfile
This patch is part of a series to improve user friendliness regarding
options for aiaiai-email-test-patchset, and improving use of the
configuration file. This patch removes the seperate [email] section, as
it really doesn't have any use. Just put these inside the global
section, since email and global really have no different meaning.
