Silencer jobs fixed

Added no hood armor option: you can get it in the entrance hall of Starmist Mansion. You need to have the original armor first.

The Silencer's vision will now make the quest advance correctly.

Silencer's vision: larger area, shorter duration, and will turn off correctly.
Radiant quests will no longer give multiple rewards.

Fixed an issue that made several Gregors stand next to the real one in his cave (for good).
Modified the scripts of the final combat again so as to reduce the probability of a crash.

At the very end of the quest, Gregor and Haeva will not stay in front of Starmist Mansion.
Reduced the area of the greater specters' spell.
Reduced the probability of a crash at the beginning of the final combat.
Added auto-saves.
First person will now be forced during the scene of Gregor's memory.
Fixed Haeva and Gregor followers.

Considerably reduced the probability of a crash at the beginning of the final combat with Uskan.

Fixed a possible crash when Uskan is hit in the crypt.
You should now be able to kill the last boss without him being 'essential'.

The normal combat music won't play along with the boss music anymore.
Deleted scripts from an other mod that I accidentally included in this one.
