#466 (Part 2) FoV Shading in Grayscale/Stripey

[Juliez]

Next one. This will add grayscaling and/or a stripey look for FoV. It also works with the different grays used for sensor range (although as before this is not very visible at low opaqueness). It doesnt affect the colored range highlighting (altho that could be added easily)
I also included these two options in the CommonSettingsDialog.Focuslost() as you did with the other one.

For the grayscaling I also checked ColorConvertOp() (far too slow) and GrayFilter/ImageProducer (far worse grayscale quality). Repainting and clipping seemed the least bad solution.

First part (stripes) was implemented in [r11673].

I wanted to make the options be in the "Tactical Overlay" tab instead of advanced options. I feel like advanced options aren't quite as noticeable, plus these options are tightly coupled with the other options in the tactical overlay.

That work got me side-tracked since I decided to make it so the options in tactical overlay would update the board view immediately when they were changed instead of after the update button is pressed ([r11672]). This is the way the advanced options work, and it's much easier for adjusting the tactical overlay settings to what you want.

Then I got further side tracked fixing some spacing issues with the components in the tactical overlay.

In the end, I was only able to get the stripes portion in. I want to look more at the gray scale option, and getting that integrated.

Implemented the grayscale option in [r11766].
