use lua headers correctly

Fix typo

Okay, remove previous request only if it has same parent as this one. Fixes the last note of previous commit (which was nearly impossible to hit, but whatever, just cleaning implementation)

- Only allow one engine instance running at the moment - When adding new map preview call to the queue, check if previous map preview request has started, and if no, remove it from queue. Could be harmful if you manage to request previews for two widgets in less time than needed to generate one.

Link some libraries needed for physfs on windows (there are still 5 symbols which couldn't be found - to be resolved)

Merge

fix deprecation warnings for libav sources

meh

linking phsyfs on osx

allow the engine to use physfs on android too

Merge from 0.9.18

Convert reading hedgehogs limit from map config

Download .zip too, and store them to .hwp

merge... need to remember to update first

Merge physfslayer branch into default. Have fun!

Close this branch

- Download .hwp files into Data folder and mount them immediately (yes, could cause problems in case of overlapped contents) - QuaZIP no more. RIP.

oops

oops

Mount .hwt files found in Data folder

oft-requested, should make the shoppa guys happy, probably, but, knowing them, I'm sure someone will complain

link main on osx

Get rid of DataManager::findFileForRead

Backed out changeset 5d00c28059e3 - enable the feedback button again

cleanup headers, remove -I . from rtl lib to save a few warnings

Use (undocumented) Mix_LoadMUS_RW to load music

mutatis mutandis

some CMake cleanup

We need custom script loading function in lua now

up android target api (but this commit is actually just to test buildbot: desync

fix build

Keeping bruteforce

another tweak tomake --stats-only work on headless servers

and install it too

Oops, didn't realize FindLua.cmake is our own module

Don't rely on hedgehog facing direction, check intentions instead. Should fix excessive turns around and weird jumps to water

comments and runtime list of files to convert and compile

Implement reader in C ffs

Pretend AI knows how to use drill rocket (actually has no idea of drilling)

finally hwengine in c links without errors

Script loading via physfs which doesn't work: - Some scripts just refuse to load for no obvious reason - Some scripts load fine when you set BUFSIZE to a large value, like 64k, but don't load with small values Error messages in both cases don't seem to have relation to lua file contents

Call fallers less often. Should hopefully still be about as effective at the intended purpose. Should help loads quite a bit.

cmake linking for engine in c

Engine loads fine with basic config

make stats-only mode work headless. also skip a few things to save time/memory.

merge xymeng's gsoc engine with a few updates (and further checks on symbol definitions)

Get rid of Pathz and UserPathz

oops

better clang search

- Add physfsrwops library - Load images via physfs (crashes)

Don't accept in-room flags when not in room

Various tweaks to recent AI change

this wasn't needed IMO
