Standardize the status.c file

Standardizes all (or almost) of the documentation for this file
Now has documentation for functions which will support Doxygen
Also standardized conditional bracketing
Removed some scopes in status_calc_speed (please double test)
Removed an unused function

'///' Is a Doxygen comment for one line
'///<' Used for variable declaration commenting
'/** **/' Standard function documentation
'//!' For TODO and FIXME
'//' Regular comment not shown in Doxygen

I apologize for conflicts
More to come, so please keep an eye out when updating that there may be updates causing many conflicts
