tiny behaviour changes to MOVETYPE_WALK (players) that need thorough testing:

- SV_LinkEntity gets called before calling touch handlers so findradius works in impact-caused touch function calls. However, area grid touching is only performed at the end of the move.
- the onground flag and the groundentity are updated after, not before, calling the touch functions (PLEASE TELL ME if this was a bad change!)
- the correct MOVE_ type is used for the touch (so spectators that have not gotten their MOVETYPE changed cannot cause projectiles to explode)
- a walk-moving SOLID_NOT therefore never causes touch functions to be called
- in case the touch function modifies the origin field, the move is aborted and a teleport is assumed; this should enable mods to make solid teleporters/portals that work at any impact velocity and are not bound by the area grid limitations of not working for big velocities
