Sidebar spacing introduces ambiguous click zones

[gary-rowe]

Panning down the sidebar with the new spacing for 0.2.0 shows a continuous link cursor. In the spaces between icon groups this is maintained leading to an ambiguous click where the user is uncertain what their target is. There is a vertical asymmetry in sidebar cell boundaries that exacerbates this effect.

I've slightly increased the spacing and the active area for clicking should now be more intuitive.

Here's a screen shot:

Ready for review and close.

LGTM - all clicks are unambiguous now. Closing.
