Change "Edit Selected Thumb" and "Edit Thumb" to "Edit Selected *Color*" and "Edit Color"

[Robert Leach]

In the color settings dialog, the third button on the bottom should say "color" instead of "thumb" to match the others.

In the color slider dialog, change "Edit Thumb" in the title bar to "Edit Color"

I was changing this back and forth and cannot decide which option is more "right" since the colors technically allow you to change value and color - or only one of them. I suppose Edit Color is still better for the sake of consistency.

[Robert Leach]

Changing the value could be construed as a color change. I mean, you're adjusting the point where the color is assigned. Thumb just seems a tad abstract from the user standpoint.

Strings have been changed.
