ayase 00777a80ae Eluna implementation (#847) 
* azerothcore + eluna done.

* Remove the Eluna single thread limit.

* Read Eluna Settings file.

* submodule change.

* fix(test)  Ubuntu - Cant Link Library after Compile

* The ELUNA is disabled by default.

* remove submodule luaEngine.

* some change

* fix a error

* change cmake

* fix: some onplayerchat does not have hooks.

* Eluna: Add BG event Hooks.

* fix:cmake hook AFTER_LOAD_CONF not work.

* Remove the eluna switch.

* Remove some define in the core.

* fix conf file not read in the linux.
