When a Snap was disabled it stopped listening to the events, but if a
drag gesture was being performed it was kept as active. Thus, when the
Snap was enabled again move events were handled as if the Snap had never
been disabled, causing the gesture handling to continue where it was
left.
When the Snap for the navigation bar is disabled by an app it could be
as a result of a different gesture being recognized by the app (for
example, a vertical swipe) once both gestures have started. In that case
when the other gesture ends and the Snap is enabled again any pointer
movement will cause the navigation bar to slide until an "up" event is
triggered again (obviously not the desired behaviour).
Due to all this now when the Snap for the navigation bar is disabled by
an app the current drag gesture for the navigation bar is ended.
Note that this was added as a parameter to "Snap.disable()" instead of
done unconditionally to keep back-compatibility with the previous
behaviour (probably not really needed as it is unlikely that any app is
using the Snap library relying on that behaviour... but just in case).

On narrow screens a slide gesture can be used to open or close the
navigation bar. However that gesture could conflict at times with the
gestures used by certain apps (for example, if the right sidebar is open
the user may expect to close it by dragging it to the right, but that
could open the navigation bar instead depending on how the events are
handled). This commit makes possible for apps to disallow and allow
again that slide gesture.
In any case, note that applications can only disallow the gesture,
but they can not enable it. That is, they can prevent the gesture from
being used on narrow screens, but they can not make the gesture work on
wide screens; they are always limited by the base rules set by the core.

The slide gesture is enabled or disabled depending on the width of the
browser window. In order to easily control that width the karma-viewport
plugin is now used in the unit tests.

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.
