When a file from the file list is dragged a drag shadow (a copy of the
file row that follows the cursor position) is created. The drag shadow
element is created as a direct child of the body element, so it needs a
higher "z-index" than the one used for the file list to be visible.
In narrow screens the "#app-content" uses a "z-index" of 1000 in order
to be visible over the "#navigation-bar" when they overlap, so the
"z-index" of the drag shadow must be at least 1000 to be visible over
the file list.
Instead of updating the hardcoded "z-index" it was removed and replaced
by CSS rules for ".dragshadow" elements to ease theming.

The selection column is not only a visual column, but also a real column
of the file list table. Unlike other columns whose width is reduced in
space constrained screens the selection column must stay the same so the
tapping area is large enough to be easily usable
The selection column does not appear in the search results table, so its
contents have to be explicitly aligned with those of the main table
based on whether the main table has a selection column or not (using the
"has-selection" CSS class in the same way as the "has-favorite" CSS
class was being used when there was a column for favorite actions).
In the tests the ":visible" selector can no longer be used. That
selector matches elements with a width or height that is greater than
zero, but the dimensions calculated in the unit tests are not reliable;
the width of the link was zero before these changes, and now moving the
checkbox to its own column causes the height of the link to become zero
too, so it no longer matches the ":visible" selector even if it is not
hidden. As hidding and showing the link is based on its "display" CSS
property its value is the one checked now.
