fix: occupied point calculation takes too much cpu power
fix: buffer overrun in messaging processing
fix: running bots on hlds 3111e (cs 1.5) on linux*
build: added back correct ldscript for gcc and clang
* for some reason only gcc-compiled binaries working on centos5.8 and hlds 3.1.1.1e. clang binaries crashing immediately, so if you want to run bot on ancient os and/or hlds you need to recompile with gcc, as default linux binaries built with clang.
fix: bots try to defuse already beeing defused bomb (fixes#116).
fix: line ending in source code.
fix: do not retreat with sniper weapon, if currently shooting and have ammo.
crlib: added deque class.
