[Mageia-dev] Freeze push: webmin

[David Walser]

This updates to 1.620.

It contains two security fixes:
- Fixed an XSS attack in miniserv error messages, and added an option to disable SSL compression to defeat the BEAST attack.

I'll need this pushed so that I can also update the update candidate for Mageia 2 in updates_testing.  I've confirmed that it builds fine in Cauldron.
