Completed a compileable build, just need to test.
- Added delay function using SysTicks
- Added seperate systimer file to emulate SystemTicks
- Added a self-enclosed delay function to libhd44780.c
-- Might consider making a seperate delay.c file?
-- Consider creating standard set of functions to ease library development on STM32 Devices?
-- Consider creating a make option to make a library from systimer, delay, any other helpful, non-standalone functions I need.
