[Evolution-hackers] tree widget padding in main window

[Not Zed <notzed ximian com>]

I just changed the shell code that lays out the sidebar in 1.5 not to add the 6 pixel padding around the tree view:

 - everyone using it thought it was weird, and not very nice to look at or use
 - it makes the paned handle look weird, especially when you can only grab part of what looks like the border between widgets
 - it wastes a fair bit of the space we were trying to gain.

Anyway, i know it was probably done like that for a reason, so Toumas, can you check this is ui guide compliant, etc?
(i hope it has exceptions for main interface windows, it looks really not great otherwise).
