Checkpoint

We were using a subclassed QTextEdit widget so that we could capture
clicks on anchors.

Moving to a delegate removed the widget per row issue.  Unfortunately,
there was no more click on anchor.

Adding a mouseEvent() to the TableView allowed us to translate raw
mouse presses to anchor triggers.

Fixes: #18
