List loss of focus triggers 'selection' event.

[jacknewberry]

List views trigger the 'selection' event when they lose focus.
This happens as the previously selected rows are reselected ( by List._blur() line 579 ) so that they get their unfocused look.

This behaviour can be remedied by changing line 204 of List.js:
from:
this.trigger('selection', {source: this});
to:
if (this.hasFocus()) this.trigger('selection', {source: this});

I should be able to change and pull-request this myself, but the github jargon is too difficult for me to understand how.
