adding 'connect as' link in the domain list, (I craved for ... and today I remembered I have commit right ;) ), and removed a _parent target in another link

Fixes #1107 : downloading a folder works indeed ! but yes, we had a file naming issue (zip or tar.bz2 were in fact zip or tar.bz2, but they were still named .tar.gz...)

Fixed #1174 : we check the length of mysql login everywhere. + english comments and misc code cleanup (hook functions at the end of the class)

 * Sur une ancienne installation, l'upgrade apache2 doit faire son boulot

remote master-key variable: it's configured on the master and propagated to the slave through /var/alternc now

we still overwrite named.conf.options and that is where we do our
includes. that seems to be relatively acceptable upstream as they mark
only named.conf as a conffile.

See: #1025

this isn't a complete fix because we do not fix existing tables

See: #1187
