A basic blink program that works off of interrupts.
- The init() function renamed to on_reset()
- on_reset() now responsible for tight-looping at the end
- on_reset() now set the VTable offset to the base of the FLASH
- included exhaustive list of irqs in isrs.i
- interrupt routines by default flash a code indicating their
isr number.
- interrupt routines are weak-linked allowing the programmer
to override them at-will.
