Emoticons constant name (#2527)

This PR change the emoticons constant name to match emoticonlist from client side.
Note: the previous emoticons names are now deprecated.

Additionnally emotion and unitemote scripts commands are being merged together to the new format
-> emotion <emotion number>{,<target>};
Where target use the target Game ID (GID) of the unit (npc, pet, character etc..).

* unitemote is now deprecated.
* Additionnally fixed incorrect variable in quests_brasilis.txt

Thanks to @aleos89 and @Lemongrass3110 !
