Added new startup command "-force_flushlog". Allows write to log file immediately (Thx alpet, RvP)

Environment_misc: fixed formatting
Added USE_LOG_TIMING. When used, log message is written in the following format: '[H:M:S.MS] log msg' (e.g. '[16:09:58.603] Loading DLL: xrRender_R2')

 When defined, it will allow you to play a group of sounds from a specified section for snd_shoot.
 You can have as many layers as you want, but you must follow naming convention,
