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

backout a few commits that desyncronized translations and broke physfs on 32 bit

merge 0.9.19 in default

fix issue #664 ("Quick game will fail if the randomly chosen theme is a DLC/custom one")
