* Consolidated is_atcommand() and is_atcommand_sub()

	- replaced gmlvl arg with a flag arg for internal/player generated checks. (dummy sds that used this arg are given gm levels)
	- each command check runs through is_atcommand() and is checked for its origin (internal or player generated)
	- charcommands are also parsed in this function.
	- script atcommand/charcommand function calls to is_atcommand() have been updated
	- also updated some clif/map functions calls to is_atcommand()
	* charcommands should now log properly with the target of the command included.
