Update fnc_isInsideBuilding

Made by @Victor-the-Cleaner

- If the player is inside a building but near a large open doorway or full height windows, or out on a balcony, they may be considered outside.
- The UI visual stealth icon will update accordingly, so the player will know if they need to step back from open doors or windows to regain stealth.
- dayz_inside global variable will now only affect player temperature, stealth vs zombies, and blizzard effects.
- The new dayz_insideBuilding global variable stores the building name the player is currently inside of, or null if player is outside. This may be used for modding purposes.
