Merge branch 'master' into Juhu/strafehud-next

variable declaration moved down to relevant code since the initialization block no longer exists
hud_panel_strafehud_wturn_alpha default changed from 1 to 0.5 to match hud_panel_strafehud_switch_alpha
removed hud_panel_strafehud_wturn_width since the wturn indicator uses the arrow style now
removed the offset_centered parameter from StrafeHUD_DrawStrafeHUD() since the old indicators which this was used for no longer exist
changed naming of some variables to match new naming:
  odd -> opposite
  switch -> change
  real -> absolute
