Outliner: Merged icon select popup UI tweaks

Adjusted some spacing and did some cleanup to the code

Outliner Cleanup: Finish renaming multi object to merged

Cleaned up the select code to use the word merged rather than
multi object for consistency

Outliner Cleanup: Move merge search to outliner_tools.c

Moving to a different file because the search is a menu and that
fits in better with the code there compared to the select code.

Outliner: Clear search on creation of merged element search menu

Rather than showing the last searched or selected element name
in the search button, clear each time the menu is created so
all the items are shown by default.

Outliner: Draw icons in merged icon select menu

Get icon for each tree element when listing the menu

Outliner: Use existing function to get unique index for element type

Just code cleanup for merged element search menu

Merge branch 'master' into soc-2019-outliner

Outliner: Show menu when clicking on aggregated iconrow icons

This is still a work in progress. The code needs to be better
and the behavior could use some improvement. It works okay for
now though.

Outliner: Rename tree element flag

Renamed from MULTI to MERGED now that I see the real name in the
code

Outliner: Draw highlights for icons in row

This draws icon highlights when the row icons are hovered.

Outliner: Fix find item at x

Now that the icons are displayed for the entire subtree, the
condition to not look past the cursor X position caused errors.
Removed and the function behaves as expected.

Outliner: Search recursively for icons in row

Rather than searching just the child list, search recursively
down the tree to allow clicking on all icons.

Outliner: Allow clicking on row icons

The feature to click on row icons was removed (presumably because
the icons now draw stacked with a number, rather than individually).
This brings back support for clicking because the benefits of
clicking on the icon without opening the element outweighs the con
of not being able to select grouped elements. A solution for that
is being worked on.

Outliner: Show active improvements

Prevent the show active operator from scrolling beneath the
allowed scrolling range. This removes jumpy redraws after the
operator executes.

The horizontal centering is difficult, because the elements
outside the view of the outliner do not have the xend properly set
and the max width of the outliner is not properly calculated.
This means it is not possible to center the x position while
keeping the view in range of scrolling.

This could be resolved by drawing the outliner after setting the y
position, but that is not an ideal solution.

Outliner: Prevent scroll page from leaving view bounds

The page up/down operator to scroll the tree could go past the
bounds of the tree leading to jumpy redraws. This prevents the
operator to go outside the bounds of the area.

Outliner: Redraw on scene camera change

This appears to be a redraw on any change in the scene..
wonder if there is a better way.

Outliner: Fix crash on duplicating scene

The function to determine if a collection was hidden was missing
a check to see if the layer collection was not null.
