Inconsistent selection methods

[nathaneltitane]

Describe the bug
timeline widget vs model space has nconsistent selection methods (cannot double click on timeline to 'red'select parts'

this issue is also akin to a problem with the introduction of the new version of the parts property widget where an apparent 'bug' was fixed where leocad now expects a double click for any selections to take effect on a multiple instance level (part or color)

this newly fixed behavior is incompatible with the timeline and the selection filters (part/color/part+color) where the whole point of these was to accelerate selection and modification of parts or groups of parts - the current result is confusing as the last selected item (model space) remains blue and is then the ONLY item to be modified.

To Reproduce
Steps to reproduce the behavior:
open model
select any component on timeline (double click)
component remains blue

effectively: cannot do a double click selection on the timeline of items and must resort to navigation within the 3d model (cumbersome and error prone)

Expected behavior
double clicking items on timeline should result in 'red' selected items.
clicking multiple items (in general, and regardless of last selcted item being blue should make filters and parts properties widget alter ALL selected parts/items)
