- Linux compatible fixes including updated makefile

Browse Source 
- Mersenne Twister still says uint32 but it's now signed for compatibility with random uses needing negative values
 - Server seed is sent to clients, but needs to be able to be signed long long later on for authentic reasons
 - Protocol Version is required to match to ensure client compatibility, this should probably have a settings.ini check as well as store the value there
