add basic modes for general creeps and warriors
creep_actions: doc fix
add build scripts for different players

My autoit script is having issues with --params
Gruntfile: default to --mode player_1
add --mode support to control warrior actions

It's in a bad spot for now, since it needs to be before we run our loop
but after we've defined our support functions (since it is called from the
loop, but calls the support functions)
spawner: make our warriors faster
creep_actions: warriors run when they lose all armor
replace strings with enums
nit
creep_actions: better 'attack target' log line
creep_actions: nit
nit
creep_actions: compiler fix
creep_actions: rename MODE to ACTIONS_MODE
util: name the enums (better for logging)
creep_actions: add meta actions for all roles
creep_actions: add return true/false to all meta actions
