Merge 0.9.17 with trunk

Improve parser and converter

Update changelog again

Oops, function call has parens

Only make AI avoid damaged dead mines and dangerously smoking barrels once the attack is finished.

Make AI be less scared by crates. Actually, now it starts using switcher just to pick a crate up.

yay, finally osx (and likely windows) fullscreen switch works like on linux! ALL textures had to be destroyed and recreated only after the new window got created. In other news, the new window must be cleaned with glClear to skip a first frame of garbage and AddProgress is only called the first time.

Make AI use switcher when: - it is immediately available - switching gains +20 points score turn

- Move actions stack out of Walk procedure - Move test for available weapons into Walk procedure

- Parse sets initialization - Render interface part of unit;

This should have been added before. add log spew if this ever happens. We should hopefully identify the various circumstances and make sure it is all cleaned up so the list becomes unnecessary.

prevent flinging up into any land.

Recognize some built-in functions

Less code

Prefix followed by prefix issue solved. Also some slight improvements.

Fix for issue #291 - this check should probably be in ApplyDamage though

Disable loading content.html on startup, it is fetched on pushing to top of stack already.

increase land tex size to 512, which is the current minimum required just to load a hat. On my system max fps rose from 840 to 890 - about 6% change. also a nil check, probably not needed.

move the order of reloading texture to workaround buggy drivers

Only recreate texture for non-empty lines

Remove a bunch of unnecessary nil checks. FreeTexture does its own nil check.

reset chat lines too

Make Highlander moar awesome.

Since I'm storing the text string anyway, might as well recreate captions on resize as well

Not useful.

Aaand in .17

oops. tex could expire, too...

Aaaand merge .17 into trunk.

merge with trunk (sound fade tweak, iOS changes)

Skip rerendering the caption if the text is unchanged. Scripts make heavy use of caption, often onGameTick
