#329 Add support for compressed webupdate.conf

[Michal Molhanec]

webupdate.conf on devpaks.org has currently cca 55 KiB
which is more than some devpaks.
In November 2004 the stats shows:
/webupdate.conf ... 6551 downloads per 52.01 KiB
which is 6551*52.01/1024 = 333 MiB per month
so in future it can have also impact on traffic limits
