Added cooldown for opening job slots for latejoiners.
Cooldown does not affect jobs for which we have previously closed a position (like how it works for closing positions)
Uplink Update:

 * Added datums for uplink items. This allows you to easily add items to the uplink in a maintainable manner.
 * This fixes the href exploit which allowed traitors to spawn any item they wish.
 * Made the uplink interface still show unbuyable items, but grayed out.
 * After unlocking your PDA, it will return to the main menu; this will help stop metagamers.
 * Your password will be trimmed, meaning that entering "213 Alpha " will be correct and won't set it as your ringtone.
 * Replaced all the old uplink code, which is useless now.
 * Changed all the feedback procs to instead use the uplink datum's name. This is important if you are keeping track of stats.
 * Moved the bundle uplink item to the "Badass" category.
 * Removed an unneeded variable.
 * Small update to check that user isn't null and that the spawned item is a /obj/item before trying to put it in the user's hand.
Fixed robots having a low charge getting their equipment state and UI out of sync.
Parrot fixes
- Parrots will now reset to wander after being stuck for long enough.

- Attacking a parrot will no longer give the attacker a "you have nothing to drop" message, that was a typical 'usr' error, woops.

- Fixed some typos in the comments.. What? That's totally commit log material!
