C++11 patchset 6: forbid object copy using assigment/copy function deleters (#5945)

C++11 implement function deleting, it's generally used to prevent some object copy
In script API use this function removal on ScriptApiBase instead of ScriptApiClient/Server/MainMenu, this affect all ScriptApis
Move DISABLE_CLASS_COPY with constructor, the deleted function permit to replace function in its original place
