Merge branch TimePath/compat_weapons

Changes to weapon names broke binds relying on cl_hook_activeweapon.

Partial fix allows the old names to be used for switching (useful when storing the current weapon in a variable), but will not transparently handle changed names in the cl_hook_activeweapon alias (too complicated).

Suggested migration path for end users: update aliases to use new names, point old names to new names.
