More minimal class icons

[LinqLover]

I patched ToolIcons class>>genericClass like this:

genericClass

	| font |
	font := StrikeFont familyName: 'Bitmap DejaVu Sans' pointSize: 10.5.
	^ (FormCanvas extent: 15.5 px @ 15.5 px depth: 32) in: [:canvas |
		canvas asBalloonCanvas
			aaLevel: 4;
			drawString: 'C' at: 15.5 px @ 15.5 px - ((font widthOf: $C) @ font ascent) // 2 font: font color: Color lightGray.
		canvas form]

Before:

After:

Of course, many other icons still look blurry or fringy, but maybe this should not stop us from gradually improving. It's not like the existing icon set was designed with perfect consistency. :D

The design question is: If we want to make such changes, do we want to make them in the trunk or dispatch some of the icon selection to the UserInterfaceTheme? I might also talk with Marcel about that ...

(or even more minimalistic: disable the icons ...

But form should follow function so I don't really want to turn them off)
