cleanup: factor out unused stopwatch code Visually, this looks a bit of a dangerous cleanup, but its not :-) To explain this cleanup: stopwatch_seconds is never used, so assign to it is useless, and the variable can be removed. Now, stopwatch_start_at_this_dive_time_seconds is not used any more, so remove it as well. Now, look at the boolResetStopwatch code. It is used but only to reset itself. This makes the whole stopwatch block in data_exchange_main.c a useless thing. All the other cleanup is trivial. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>

;* Description        : STM32F412Cx devices vector table for MDK-ARM toolchain. 
;*                      This module performs:
;*                      - Set the initial SP
;*                      - Set the initial PC == Reset_Handler
;*                      - Set the vector table entries with the exceptions ISR address
;*                      - Branches to __main in the C library (which eventually
;*                        calls main()).
;*                      After Reset the CortexM4 processor is in Thread mode,
;*                      priority is Privileged, and the Stack is set to Main.
