In ARL.lua: Removed all upvalued F_WHATEVER constants, replaced usage with private.filter_flags.
Renamed private.acquire_flags to private.acquire_types.
Added new table members to the private namespace: rep_levels, faction_ids, and faction_strings.
In ProfessionDump(): Recipes with no specialty will no longer print "nil". Recipes with reputation acquires will now print the faction name.
Added "local REP = private.rep_levels" and "local FAC = private.faction_ids" to all database files to accommodate the new dump output - retained the current reputation level constants until the databases are updated.
In Player:HasProperRepLevel() and Player:IsCorrectFaction(): Replaced local faction values with lookups in private.faction_ids
