Arma 3 RAM limit increased to 3gb (64bit only, startup paramiter)

[Don_prince]

plus the increase to 3GB limit is back, hence -maxmem=3071 works in profiling and even stable
it's part of the new memory rework (related to 64bit cleanup of code/changes) so we re-enabled it
thus some feedback on that would be quite welcome too ...
note: 3GB limit for maxmem is available only on 64bit OS, on 32bit OS it is still 2GB
note: use startup params from steamclient as Arma 3 Launcher own settings are limited to 2047 until next update
