Restore hud notify area

[SamVanheer]

The HUD notify area is located in the top left of the screen and used to contain text printed to the notify area (see HUD_PRINTNOTIFY).

An update to the engine broke notify printing. It should be possible to re-implement this by using cl_enginefunc_t::Con_NPrintf or Con_NXPrintf.

Check the original version of the game to determine how notify printing was done to match the original behavior.
