Added emissive textures

fix negative rented room time

Also, I rewrote CheckRent() because it took me a while to understand
that -1 was a magic value for remainingHoursRented. The logic should be
unchanged.

fix a NullReferenceException in DaggerfallVidPlayerWindow.IsPlaying

LoadingScreen uses player.IsPlaying to poll when a video is finished
playing, but the video may have been cleared

skip climbing/rappel mode checks when not on foot

Prevents trying to rappel down on horse or cart, for example.

prevent clicking on EXIT while amount input in progress

Seems to confuse some people, that input some amount, close the window
and expect the transaction to have happened.

Another solution would be to open a dialog box to input transaction
amounts; But it doesn't match classic screens.

remove LegacyDeferred setting

It seems to no longer work correctly with recent Unity, it's becoming a
way for players to shoot themselves in the foot, so drop it altogether.

Are there anything to remove beside camera.renderingPath tweak?
