this was getting annoying, don't error out on warnings physfs

ok. this could be tidier, but, I'm sick of hogs w/ unmodified thaw thawing on exactly wrong turn.

make sure that also CXX sources pick up the flags (although I'm not 100% of the correctness of the tests)

add fstack-protector and fvisibility=hidden to cmake tests

also apply linker flags to haskell programs

add relro linker tests (issue #663)

move compiler checks in a separate cmake module

simplify cmake message syntax a little bit

move platform specific and revision info code into separate cmake modules

update changelog

move 0.01 to the end to avoid increase damage fail on small values like fire. thanks to hedgewars wiki for noting this for fire damage.

add note about mudball causing no direct damage to changelog

close branch

Fix more warnings (lol @ icegun "consts")

Skip some LandPixels manipulations in stats-only mode

Merge

Fix script flaw in detection of best team when sending achievement info

Bump protocol and version (game desync would be triggered by b70352db5675, 2ae44c4381cd - other revisions probably safe)

Fix build

Restore CurAmmoType check as well, that was removed in r8f317ba10675 when trying to fix aiming during alt attack. This probably fixes bug #657

Store TrophyRace records in database

fixed all engine compilation hints and notes (that I could see)

parsing ok, stops at uGears

Declare achievements in console statistics output

fix last remaining warning in frontend

actually everything is CLANG'd

moar cpack ignore

Hedgewars.png had a resolution more than twice as high as required; also fixed some (mostly obsolete) code that also contained a typo that would cause a warning/note in clang

move sdlmain_osx aside in its own folder so its include path is not contaminated

sigh, this follows r63bf1f4f40f8

good-bye QAspectRatioLayout

update branch
