* Converts move intents to /decl/move_intent
Adds /decl/move_intent/walk and /decl/move_intent/run.
Switches all move intent checks to use the new IS_RUNNING and IS_WALKING macros.
Renames and refactors /mob/living/proc/set_m_intent() to /mob/living/proc/set_move_intent(decl/move_intent/intent).
Removes the unnecessary /mob/var/m_int and associated code.
Updates all move intent setters to use set_move_intent().
* Swaps incorrect config values
Swaps incorrect move delays since I got them backwards somehow, oopsies.
* Adds suggested ?. operator
Compactifies two if statements using the ?. operator instead.
Don't snowflake one mode with new(). Setting this on new() causes
weirdness when new() is called (prints unexpected messages to players
about the mode being toggled). If you really want it, define the var as
equal to the bitflag in the definition and update the starting human HUD
to match. Don't change it 'after' if that's always how you want it.
Manually ports https://github.com/Baystation12/Baystation12/pull/12614 's fix to not make examining trigger the autofire.
The toggle to shoot if the target talks on the radio defaults to off.
The aim intent icon now updates when clicked.
