Adding configurable DebounceDivThreshold

Browse Source 
Can be specified from any .kll file

DebounceDivThreshold = 0xFFFFFFFF
Sets to max debounce, default is 0xFFFF.
The 0xFFFFFFFF is about a 2x longer debounce
The max requires more ram (as it uses 32 bit variables instead of 16).

Added support for submodule capabilities files.

# This debounce scheme uses a rolling counter for press/unpress on each key
# Each counter is incremented if pressed/unpressed and the opposite counter is divided by 2
# Using the default division threshold (0xFFFF), there are approximately 13 cycles in a perfect cycle
# If debounce is actually necessary, this will increase (better switches will debounce faster)
#
# The maximum threshold is 0xFFFFFFFF, which will give around ~32 -> 36 cycles per perfect cycle
# Using a threshold higher than 0xFFFF will require 32 bit variables, and double the ram usage.
