Cvars: Rearrange a bit some code

Browse Source 
Changed class CCVar -> struct CvarInfo
Added CvarManager class and moved some code there
Code of registering a cvar is rewritten
Cvars datas are stored in a hashtable for fast lookup
For natives compatibility, an inline list is kept (though CList -> ke::InlineList)
Replace some CVAR_GET/SEt_ by FindVar
