clean up image loading a bit. gets rid of useless "Passed NULL data source" or PhysFS file not found errors

committing patch from issue #798, as requested by unC0Rr

fix cabal build (on linux)

fix for "Unexpected semi-colons in conditional" issue, as reported by YuGiOhJCJ (see http://www.hedgewars.org/node/5860 ) big thanks to burp for helping to identify and fix this issue

Some further work on map optimizer

tweak untint a little (especially in connection with GrayScale)

theme configurable sudden death music. untested

allow teleporting outside Land[]

escape info message arguments, fixes issue #801: Frontend parses INFO command output as html

collision indicator on failed girder placement (especially useful with rubberband I guess). still needs some tweaks but I am going to bed now :P

disable these weaponset flags. they bug up highlander and otherwise have no useful impact on the script.

get rid of fpc warnings/hints

Fix some of issues found by coverity

Official racer challenge map #8

Inform frontend of lines which didn't change anything on the map in advanced drawn maps mode

Fix some pas2c engine warnings

Count number of pixels changed during draw

Small optimization (no need to draw last point of the path)

Oops, should stop coding at night

Fix fpcrtl_strncompareA, also replace strncmp with memcmp for more efficiency

Support OR operator in $IFDEF. Fixes pas2c builds.

rolling back the rest

rolling back (most of) lua 5.2 compatibility patches. hopefully that will unbreak unC0Rr's lua issues for now.

sekret feature (test commit)

- Increase limits on number of mines and explosives in game scheme - Stop trying to place mines/explosives after 4 fails to place in row

Drawn maps optimizer - first steps: - Break paths into segments

Fix crashers in rc plane code

Merge

don't search for lua 5.1 anymore

Don't activate invulnerability/vampirism between shots of multiattack weapon

minimal changes for compatibility with lua 5.2, thanks to v4hn for fixing standard library loads. note: ALSO compatibile with (internal) lua 5.1, until something bothers to upgrade bundled lua version

Fix typo leading to crashes

Add race type detection

- Fix bug with infinite rounds in racer when a team quits mid-game - Don't allow placing waypoint right on top of previous one, prevents accidental double waypoints - Don't limit maps on number of embedded waypoints

Fix new generator on 32 bit arch

No more occasional long straight edges

Spelling corrections

Optimize out path closing point for one point paths

Racer challenge map #7

Official racer challenge map #6

merge

param for original highlander mode - right now just allows getting another copy of a weapon you already had, but had used that turn.

Send updated info on map switched by voting

Fix condition

Fix build

- Fix applying vote result - Votes expiring (I'm sure it doesn't even build, but my ghc is broken for now, hoping for the best)

Fix script

Racer challenge #5

Some fixes to voting + small refactoring

Better detection

hm. I think I forgot to commit this when adding speech bubble change

Fix warnings

- Limit outline to leftX/rightX/topY instead of LAND_WIDTH/LAND_HEIGHT - Fix most of templates which could produce self-intersecting polyline as a start for distortion - Fix parsing in templates editor

- Make sure distortion doesn't move fill point to other side of segment, this prevents corrupted maps - Some adjustments/comments

Process segments from last to first point too

Prevent intersections with segment from last to first point, adjust size of details

Fix div by zero error in new generator

Greedy approach: divide while it divides

No self intersections, except for weirdness between first and last point

Fix detection of intersections, still need to check if passing any point in move, but result is already okayish
