Add icons for dark theme

[Cqoicebordel]

In a dark theme (breeze-dark here) the icons are barely visible. An image is worth a thousand words :

I do had a plan to add light color icons, but had no time yet. Valid feature request.

Note that :

• Ksnip is also affected (just in case you didn't notice)
• Since all icons are SVG and in a single color, it might be possible to change the color dynamically depending on the theme, either through modification of the SVG itself (by populating the colors dynamically), or through CSS.

[DamirPorobic]

Yes, I'm aware of it. I will probably create a light set of icons and add a loader which checks the theme color and loads the correct icon.

[Cqoicebordel]

That's what I meant : You don't need another set of icons, you just have to set the fill, and the fill stroke of the SVG, to the OS theme value.
For example, http://cqoicebordel.free.fr/SVGExample/. The color is changed via CSS and nothing else is done (it's twice the SVG present in your repo (a bit cleaned though)).
And you can do that using myPushButton->setStyleSheet("* { fill: blue }");
See http://doc.qt.io/qt-5/stylesheet-syntax.html

(I'm not familiar with the C++ side of Qt, so I might be mistaken, but QStyle could do the same, I think)

[DamirPorobic]

Might be working, but I had bad experience with QStyleSheets in the past as they could behave differently on different systems, so usually use them as kind of last option. kImageAnnotator should not be the problem, all icons are svg, in ksnip however, some icons are png and I've tried recently to port them to svg but the small ones look blurry due to downscaling. Upscaling looks ok.

Added support in ksnip too
