Fixes #857. Wrong attribute name on a namedtuple.

ActionInfo class created as a part of the ShortcutManager changes in
Volumina is a namedtuple. It does not have a setEnabled() method.

This code path is triggered when pixel classification is used with a
color image and a new label is added for instance.
PixelClassification: Fix shortcut context widget for uncertainty layer.
bin/labelcounts: Fixed bug if the max label is not present in some blocks.
shell: Re-enabled settings menu for non-debug users.
labeling: Don't auto-enable the "add label" button just because the user switched brushing color.
OpVigraWatershedViewer: Added some example code to __main__ section, useful for manual experimenting.
bin/labelcounts.py: Removed debugging code.
shell: When saving profile text, auto-open the resulting file as a convenience.
PixelClassification: Replaced OpBlockedSparseLabelArray with OpCompressedUserLabelArray
OpPixelClassification: Removed obsolete OpShapeReader helper.
DataSelection: Print traceback on error.
tests: testSerializer: Use OpCompressedUserLabelArray instead of OpBlockedSparseLabelArray
Removed unused import
example labeling applet: Upgraded to current codebase so it works again.  Also, use OpCompressedUserLabelArray instead of OpBlockedSparseLabelArray
tests: gui tests: Create temporary project file in a temp directory, not in the source tree.
Bumped version: 1.0.2
