Base time formatting adds + or - in front of the timestamp, so the column has
to grow a little to not hide the last digit.

ColumnManager has to apply the zoom factor to newly added columns. Otherwise,
showing a previously hidden column appears with scale 1.0.
This also drops the value-changed signal emission for the vadjustment, as it is
apparently not needed.
Add two actions to shrink and enlarge the text in the log pane. Add a theme
overide to set expander size to 1 (see bug #615985) and also turn focus lines
off. Remove extra ypadding on cells.
These also appear in the context menu of the timeline. The more generic wording
