Fix #1359 (VOR/NAV gauges missing yellow ticks; needle center off)

[hbeni]

This adds yellow ticks and the OBS label to the knobs. (fix #1359)

• Texture was redone in texture repository (see Fix Issue #1359 @ c172p c172p-detailed-liveries#4)
• VOR1 blend file was adjusted to reshow the Face texture again (the ticks are placed on the transparent part, so they are in the foreground and not off the ring when viewed from the side; the outer part of the face is still hidden from the cockpit panel)
• VOR2 was redone as a fresh copy of VOR1, because the face was off.

This PR also fixes the localizer needle rotation center.

Please verify toroughly, especially on the cockpit effects and stuff, because I'm not proficient yet in that area.

Localizer needle center was off also (top: corrected; bottom: old values):

Thanks @reiszner for spotting this!

I also did check the glideslope needle, but that looked good already.

@wlbragg had you time to check already? Or is there something you want me to change?

[wlbragg]

@hbeni no I haven't been available for FG lately. I'll try to get this reviewed and merged soon. Thanks for reminding me.
