Explode Verb Fix
- Explode verb is now available from round start. This ensures it works properly and won't disappear during 60 second time limit.
- Checks are moved into explode verb itself, so it works exactly as it used to work (read: It won't let you blow up station unless done within that 60s limit after takeover)
- Changed self destruct notifications a little. They now use radio messages instead of "world <<" which was ugly.
- If AI is killed within 10 second self-destruct countdown it is aborted. (Good luck)
