Evolution inconsistencies

[ghost]

1. After fixing #119 icons became hidden from right side (1px).
2. Misaligned icons. Adwaita looks more consistent here, so it is possible to align them.
3. 2px border makes it inconsistent with 1px box above it. See second picture — border width is not uniform across Evolution tabs (memos, notes, etc.)
4. Columns are not separated (not sure if it is possible to fix it). Nautilus as an example.

1. While I couldn't reproduce, I removed the left and right paddings.
2. ^
3. Not much that can be done about it without risking other applications to look strange. I don't like adding application specific fixes unless there are unique CSS classes that I know for sure isn't used anywhere else.
4. It's one big single table header. The Evolution developers should use GtkTreeViewColumn instead of that thing they're using now.
