- reworked CVARs to not use a linked list and to be initialized manually.

Browse source 
This solves two problems:

* The linked list is too slow, a map is better. A map cannot be used with statically allocated CVARs because order of initialization is undefined.
* The current CVAR system is an unordered mishmash of static variables and dynamically allocated ones and the means of identification are unsafe. With this everything is allocated on the heap so it can all be handled the same by the cleanup code.
