Debug icon polish

• breakpoint-hint icon back
• start icons in dropdown and toolbar are the same size now
• breakpoint icons in viewlet are set to 16x16 (the original size at 100%).
• restart icon is slightly smaller now.
• breakpoint icons in margin size - there is an inline css rule that has calculated icon size based on editor line height. The default line height is 19px. That's why they look bigger than before (hard-coded size inside svg files). I personally don't mind this. If you think this is an issue, maybe we can add a css rule to force the margin icon size at 16x16 at all time?

Good work. Some feedback:

• imho the continue button is too smal compared to the other in the debug toolbar, might need a bit more size, or the step over should be shrinked a bit. This is personal preference so if you disagree no action is needed

• Breakpoint still looks larger than before in this screenshot I am comparing latest to stable. Edit: sorry only now saw your comment - yeah I think in stable it is already too prominent so increasing the size will just make it worse, so I would hardcode the size. Or leave it dynamic but that it takes a smaller portion of the line height

• Breakpoint-hint icon still taking priority. Might be just some css tweaking - I can look into it if you want (I would try to add less specific rules to the hint so it loses to everyone else)

• Agree. I'll balance these two. I made the red square bigger when I re-worked the "disconnect" icon to fit the little plug. The green arrow is actually the same height but being a triangle makes it look smaller.
• Let me reduce the base size even more and keep them dynamic.
• I haven't figured out how breakpoint-hint icon works. The svg is same as the regular breakpoint.svg except the path has 40% opacity. I'll leave this one to you.

@chryw sounds good, you can provide a PR for the first two, and I will take care of the breakpoint-hint. Thanks a lot

We forgot to update the css rules regarding breakpoint-hint. I have fixed this via b564529
Now all is good regarding breakpoint-hint
