merge the changes applied to 0.9.16

Blend the outter side too

Hide focus outline on buttons.

oops

Add SkyL/SkyR to avoid repeating the cave entrance

Remove unnecessary assignments post-creation. Simplifies Lua manipulation of these adds as well as just being tidier.

another crystal, spray and landtex tweaks.

something for nemo to play around with

make slope calcs skip small gaps

tidier

Make sticky mines and normal mines start their typical behaviour a second after creation in infinite attack mode.

set followgear to cluster/melon/gascloud

Make a few more things be impacted by explosions nearby

tweak (still a hack)

Experiment in making ice more treacherous. also tweak to snow/christmas flake spawn

Aaaand another flag that used to be cleared here...

HUGE refactoring of the ipad interface, finally understood how to use interface builder with custom uiviewcontrollers, as well as converted some uitableviewcontrollers to uiviewcontrollers for simplicity

expose border color to lua

oops

Restrict slipperiness to girders and bridges. Make girders more obviously ice.

Fix a few masks. The one that needed it the most was trophyrace.

add a couple more

finally removed the white border glitch of the ipad preview map, moved initialization from IB to code

refreshed the ipad interface with some white

some code refactoring of the ios game config

ooops

move some config files

create teams programmatically

convert creation chamber functions to class methods

Updated Slovak translation

merge

sed commands should be tested beforehand

Another flag that was relying on this routine to clear it...

tweak Y movement

Couple more, add back misplaced clearing of Land

Add landbacktex to a few maps, just to see how it looks.

minor changes

added iphone interface for missions/trainings page, setters/getters unlocked

move out xib files from Resources to Classes

This should allow hedgehogs to still move freely after trapping other hedgehogs in a portal loop.

Move the crystals to sprays to reduce the regularity of the land texture

Add Cave theme

(a lot of) ooops

- Frontend: don't pass /script for missions - Engine: try to load script for map (not tested)

Tiny cleanup

the retina infection keeps spreading...

be a good memory aware citizen

make the missions/trainings start

first pass for implementing missions/training selection on ipad (not yet running)

hm. probably should set both

Basic test implementation of an ice flag. Allows for slick parts of terrain. Intended for ice gun, or "ice" mask on portions of land objects. In this test variant it is triggered on girders/objects/bridges of the snow/christmas theme, or on a map that uses blue as a mask colour. Probably needs sheepluva's slope detection to make slopes more slippery to climb.

on ipad2 and above animate the little hogs on game config and fix the hat display imaging

little changes and fixes to the previous commit

headers cleanup, converted some function-only sources into proper class method files, more use of OOP power, removed some 'respondsToSelector' calls, moved defines into their own header, more use of objc categories

This prevents girders from erasing landbacktex (square windows in tunnels and such), at the cost of requiring lfBasic and lfObject to be treated the same apart from graphically

fix a couple of 'potential leaks'

rename the ios settings files into something more appropriate

ios major refactoring for ios settings, now they are presented differently on iphone/ipad, code is simplified and optimized, and ui is a little refreshed (eg. no more stuck selected fields)

infecting sheepluva's mission graphics with retina images

a little code cleanup
