[CLOSED PR] Nerfs the departure time reduction on emagged shuttles

[Tribaja]

I mean I dunno. Its not really over powered because its just the shuttle? All that happens is some people don't make it to centcom. Emagging the shuttle has always just been a HAHA GET LEFT BEHIND thing or someone does it for their traitor objective. Maybe I'm just part of the old mindset of SS13 player that finishing objectives or getting to centcom doesnt really matter that much to me.

 This and even with 10 seconds there's usually a huge mob already waiting at escape when the shuttle arrives who will get in, making it even harder to get the "escape alone" objective if somebody really wants it. Emag is pretty much the only way to get that, unless you go specifically to a lower pop server to get it and even then it's going to be markedly harder if the time is upped.
