[8608] implement BattleGround Alterac Valley

sql won't be included - please look at your database
providers forum

also note, that creature_loot_template id 0
is used for the loot of dead players in this bg
(after a player died and you remove insignia from him..
he not only drops money - he drops some random items too)

further work must be done in better code for adjusting right
levels to creatures - maybe using something similar like it's
done in heroic instances

also quests and creatures needs some scripts in future

thanks to:

arrai - for his great tool and help
and all testers / code contributers - I won't write
down a list, else I would forget most probably one ^^
