Created Time class.
Space.
Added to time to makefile.
Upgraded thread_killer's clock to a steady clock.
Made get_dt() called in a slightly less odd way so I can work towards removing it.
Turns out that codepath didn't do anything at all... removed.
Pointless newline removed.
Removed <chrono> from main.
Have to rename Time to GameTime due to stupid typedefs in X11 and a lacks of namespaces. :(
Fixed makefile.
Converted completely to using GameTime for times.
Merge branch 'master' into font-rendering
Integration with makefile
