Pychan widget events

[vdaras <vasileiosdaras@…>]

Make event mapper able to map events distributed by widgets.

Possible widget events:

• Widget hidden
• Widget shown
• Widget moved
• Widget resized

[vdaras]

(In [3941]) Enabled widget events. Events widgetMoved and widgetResized are not fired for children when their parent is moved or resized yet. I also created a test in <fife>/tests/fife_test/tests/ for this. refs #705

[vdaras]

(In [3942]) Updated settings-dist.xml to include PychanWidgetEventsTest? refs #705

[vdaras]

(In [3943]) Fixed a bug in <fife>/tests/fife_test/tests/PychanWidgetEventsTest.py refs #705

[vdaras]

(In [3955]) Removed pychan widget show/hidden event distribution since widget re-distribution is now handled at fifechan level.

Events for 'widgetMoved' now work too. refs #705

[vdaras]

(In [3956]) Changed widget events in pychan.

Introduced three new events -ancestorMoved -ancestorHidden -ancestorShown

Now a widget that its parent was e.g moved fires an ancestorMoved event instead of a widgetMoved.

Also updated the corresponding test to demonstrate the new events. refs #705

[vdaras]

(In [3957]) Made another update in test for Pychan widget events. refs #705
