Minimize SendTo and Read Socket Timeout Delays

Browse Source 
SendTo and Read were using longer than necessary socket timeouts that may add to process time delay and stuttering.  They were also using different values between Window and Linux/Mac.  The timeouts are now standardized for all versions and coded in the same manner as the xplaneConnect.c functions.
