v1.1

- added sound alert for every new mob that gets aggro. (instead of just when a player enters combat)
- added settings window. access by typing: /aa
- added more sounds.

P.S. If you want to add even more sounds: 
1. go to: https://www.wowhead.com/classic/sounds
2. download the sound you like and add it to Interface\AddOns\*\sounds
3. edit the "core.lua" by adding new line to sounds
4. example: local sound_files = {
    ["How are ya?"] = "Interface\\AddOns\\"..ADDON.."\\sounds\\aggro.ogg",
    ["Cyaaa"] = "Interface\\AddOns\\"..ADDON.."\\sounds\\ok.ogg",
	["NewSound"] = "Interface\\AddOns\\"..ADDON.."\\sounds\\newsound.ogg"
	...
}
