BUG: #3076 make sure scalar range is updated after edit operations.

This new method unifies the updating of the image data and volume
node to trigger rendering.  By calling modified on the point scalars,
this GetScalarRange call returns the correct data.

http://na-mic.org/Bug/view.php?id=3076

This is confirmed by looking at the results of the call after
editing in new colors as shown below.

>>> l = getNode('*label')
>>> l
(vtkMRMLScalarVolumeNode)0x131766ba8
>>> l.GetImageData().GetScalarRange()
(0.0, 15.0)
>>> l.GetImageData().GetScalarRange()
(0.0, 18.0)
>>>

BUG: Fix spacing buttons in slice controller widget

Ensures automatic spacing button in slice view controller widget toggles automatic spacing on and off, and updates the icon in the widget to reflect the spacing mode. Ensures automatic spacing, manual spacing, and field of view buttons are synchronized with MRML slice nodes. Ensures automatic spacing, manual spacing, and field of view buttons for each of R, Y, G update together appropriately when linked. #2993, in part similar to #2676-2685.

BUG: External link in extension manager now open in browser. Fixes #3045

To determine if a link should be open in the extension manager or in an
external browser, the "host" of the clicked url and the server url are
compared.

BUG: Fix lost on focus when modifying spinbox

Previously, the spinbox would lose focus when modifying the value due to
an update by the node. Using the new ctkSpinBox that actually checks
if the values are the same before updating fixes this.
