Time for 0.9.17, or the belated anniversary release!

Well, initially this was supposed to be a quick release to fix a few bugs in 0.9.16 and throw in a feature or two.

But, things took a couple of weeks longer than planned, and along the way, some other fun stuff got added!

Let's see... New theme, Cave. Fight amongst translucent crystals in a cave underground, endless dripping builds up stalactites and stalagmites, and the light from outside illuminates the cold gray world.

New voicepack, Hillbilly. 'Nuff said? Yeehaw!

AI is now smarter. Now with the ability to switch hogs, you may find it is not quite as easy to defeat a horde of AI as it used to be. More improvements planned in future.

Frontend revamp. More attractive missions screen, timestamping and links in chat, DLC page refreshes on access, chat styling, and a fix for a frontend crasher.

Ice. This is for a future ice gun, but for now you can try it out on the bridges and girders of the Snow/Christmas theme, or on any static map with a mask that uses blue.

A number of small graphical tweaks. 3D modes should look more 3D now (clouds/flakes), girders don't leave windows when placed in blowtorch tunnels, static maps can now have background land.

Aaaand of course, the bugfixes...

See the ChangeLog as usual for a bit more detail.
