Bforartists: Improve Text field highlight colour

[Draise14]

Theme update Request
The text highlight is a saturated blue, and the text cursor also - which makes it hard to select a text field and edit it.

I suggest to make the text field the same as the number field.

Example of contrast issue

Describe the solution you'd like
Better contrast on highlight.

Describe alternatives you've considered
Maybe a darker blue? Less saturated?
Make it the same as the text field?

Draise, what exact edit box is meant here?

[ReinerBforartists]

Now i see what you mean. The caret is hard to spot. Let's have a look for a better color that doesn't conflict with other edit boxes.

The caret color would be more interesting here ...

[ReinerBforartists]

Bad karma. The caret color seems to be hardcoded. And i have no idea where to even start with the search.

Sliders have the same problem than the text editing props. And changing the color of the slider is no good idea. It is what identifies the slider as a slider. Perfect trap -.-

I would just change the highlight of a text box to just lighter grey, same as sliders, same as number boxes.

Theme>Interface>Text - change Inner Selected from blue to same grey as elsewhere (it's inconsistent anyway)

Fulfilled as requested :)
