Add crosshair cursor and or logic options

[jking-bro]

adding two settings options (and their corresponding functionality)

One to enable/disable switching the cursor to crosshair during selections.

The other allows the user to choose to trigger column selection using EITHER (new "feature") or BOTH (old behavior) the selected mouse button/key.

By default, the behavior of this package will not change. Users will have to go to settings & adjust manually.
