removing sendstats(uScript) from luaAPI

created a new sendstat type for changing the kills label

fix non changing graph title and sendstat health

correct health statsend for lua scritps

added option to change stats graph title

made lua scripts able to turn off automatic game stats

LuaAPI sendstat finds correct clan colors by team names on siPlayerKills

added custom stats message

More verbose initialization

visibility unsupported on windows

Some fixes to make pas2c+clang compile all engine files

protect all types with -fstack-protector-all

- Fix 'and not' without parentheses - Better detection of such occasions

stack-protector flag needs to be passed to the linker as well

Allow building with modern 'base' package

port all Q_WS_* to Q_OS_* so that we are forward compatible with Qt5

lua warning with clang

These could be handy

update with default

set linker flags where appropriate

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
