Pop up a confirmation box when there is input. This prevents accidental closing
of the dialog boxes due to clicking outside.
This adds a development hook on modals in the form of a `beforeClose`
function. Modal windows can abort the close if the funtion returns false.
Additionally fixing a few issues with loop and state on the modal popups:
Escape key with bootbox is keyup.
Updating modal to close on keyup as well so escape key is working.
Fixes an issue where pressing esc will loop immediately back to the modal by:
keydown -> bootbox -> keyup -> acts as "cancel", restores modal
Needs a next call to reopenModal otherwise, keyup is handled again by the modal.
Fixes an issue where pressing esc will loop immediately back to the confirm:
esc keyup will be handled and bubble immediately back to the modal.
Additionally, only handle key events when the #discourse-modal is visible.
This resolves issues where escape or enter events were being handled by
a hidden modal window.
A modal's primary action (blue button in the default theme) can now be invoked
by hitting Enter on the keyboard. This applies to all modals that aren't strict
forms as long as the focus is not on a textarea element.
This happened because the modal controller was not clearing the `name`
attribute, which is used for looking up the controller to call `onClose`
on.
Every page navigation would call the method over and over, breaking
state in odd ways.
