Sidebar tooltips nitpicks
I found a few nitpicks in the sidebar:
- "Open Pages" labels can be disorienting when the ellipsize hides the path to the file (it ellipsizes on START). My instinct was to hover and wait for the full path, but there was no tooltip.
- The tooltips for the "Project Tree"/TODO/Build froze in place while you hovered over other items. The text would change but the tooltip itself wouldn't move. Turns out there's already a GTK+ function for that!
Also did a few quick cleanups along the way.
