Selection management control

[zspitz]

An independent control, for managing the selection of another control.

Can be used with DataGrid, ListBox among others.

• Text filter
• Select all
• Clear selection
• Invert selection

Properties:

• Control (wire up in code, for now)'
• Filter member path - path on which to apply filter

Rather than trying to find three buttons with recognizable icons for changing the selection, have a dropdown button next to the text filter, with the three options.
