Tours Castle and Johannsvall map markers

Added castle marker (Imperial Legion) and Jorrvaskr (companion) map marker.

For some reason, the headquarters of Skyrim's two main factions don't have their own map markers without the opposite numbering. This makes use of two unused icons from the game data, adding map markers for the Imperial Legion HQ at Castle Dour and the Companions HQ at Jorrvaskr, alongside the existing icons for Stormcloak HQ at the King's Palace, and the Academy of Winterhold. (Yes, there are many other mods that do something similar, but I can't find one that adds just those two markers and nothing else.) Both are standard "reveal on discovery" markers and allow for fast travel.

Notes on fast travel

If you use the Jorrvaskr marker for fast travel, be aware that you may inadvertently bypass certain quest triggers elsewhere in Whiterun.

Vikas may not be waiting for you outside when returning from Cain on the Dashman during Proof of Honor, as the trigger to move him outside is located at the Whiterun main entrance. You will need to walk inside to find him, or go back to the front door to activate the trigger. (This is also a common error that can happen whether you enter Whiterun quickly or not.)

While returning from Glenmoril Coven during Blood's Honor, a group of punks were supposed to comment on the scene outside Jorrvaskr. The trigger for this scene is at the bottom of the step, so you need to go back to the step to turn it off.

I don't see any significant scene triggers near the Castle of Tours, so there should be no problem.
