Some token efforts to make singleplayer mode (accessible only via -warp and map mapxx -force) not COMPLETELY broken.

* Fixed the conditionals for `suicide` and `retry` commands - `suicide` is now allowed in singleplayer, and `retry` no longer checks your lives (for now).
* Disable the "traditional" level reload method (which `retry` tried to use), since it was completely broken with the other changes we've made. Mapchanges only.
* Made retries cause a mapchange, per the above.
* Disable the last source of skincolor trampling in the game - loading a level while not netgame or record attacking.
