  50 Improved version of normal trigger_push.
  51
  52 Pushes anything that touches it,
  53 or acts as a jump pad, hitting "target"
  54 at the apogee (peak) of the jump.
  55
  56 Target should be an info_notnull.

  58 Flags:
  59 "PUSH_ONCE" - removes itself after push
  60 "SILENT" - no 'windtunnel' noise
  61 Keys:
  62 "target" - acts as jump pad, hits this entity
