Syndicate Bomb tweaks

-Visible timer added when examined
-Needs to be bolted down before it can be used

The changes were done to prevent the bomb being used as a grenade, holding onto it and hiding until the time was low enough to just chuck it into a crowded area. It also prevents players from hiding it in disposals or a locker, which made it near-undetectable. Being able to tell how much time is left will also promote tense bomb defusal situations
