- fix the "teleporter causes 'sprint to non-client'" bug

- prevent building when a teleporter is too close to a wall

BUGS

@@ -4,7 +4,6 @@
 - "has_sentry" should be a counter, not a flag (allows a second build if you hack and it gets roasted)
 - there appears to be a window between when a teamkill curse respawn is disabled and when they're killed.  it should be removed.
 - through some combination of respawning, respawn guard, and teleporters (not necesarily needed), it's possible to get stuck on another person
-- if you build your teleporter too close to a wall, and it blows up, you get "tried to sprint to a non-client"
 - hacked forcefields get you teamkills
 - the "speed cheat" checker needs to be ripped out, it's kinda useless
 - sometimes rockets go through armor..

TODO

@@ -19,3 +19,4 @@ o  "slave teslas"
 o  instead of not allowing two fastest legs when upgraded, restrict the health/armor you're allowed when you have fast legs
 o  make a seperate menu for detonating engineer buildings
 o  remove RPrint, since it's really kinda pointless and just makes the code ugliero  change the color defines (eg DARKBLUE) to be the exact number, not number + 1
+o  remove the old method for teleports checking if blocked, after confirming it's not needed.  (moving platforms block it?)
