make enums crash-safe. and other fixes

WIP: PlaceSprite for lua API. also changed PlaceGirder so that it will return true/false for whether placing was successful too

fix possible engine crash that a lua script could cause by passing an invalid geartype to addgear

tiny lua documentation fix

uWorld does not require uMatrix anymore

fix hint and gl2 build. NOTE: this does not change that GL2 segfaults right away. that is an issue that dates back at least 50 commits, but most likely even back to the webgl merge. I guess nobody actually tried to run hedgewars in GL2 since back then :P

RAR: cleaning up a bit of the IFDEF-clusterf*ck

Fallback to old heuristic if not pit position

update viewlimits after screen/window resize

Allow barrels to spawn in U-shaped pits in stable position

whoops, forgot to include this file in commt

superminor tweaks

<koda> wut, chats as commit mesages?

"<unC0Rr> could also refuse to update textures when land changes if the tile isn't visible" You had me at "refuse" <3

figure out visible land tiles in advance

some minor tweaks and stuff

darken wrapped areas, which was a very nice suggestion by nemo

use cScaleFactor where I incorrectly used the variable zoom in the past. i was young and needed the money

here a personal experimental mockup of how I imagine wrapping world edges should look like. bouncing one could be similar just with mirrored stuff. please test and share opinion. note: you might wanna disable auto-cam

small hat loading tweak

load the girder.png of a theme a maximum of 1 times (minimum of 0), instead of once per generated bridge

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
