Fix issue with toggles blocking dialog and dialog launching on mobile

[donkawechico]

Proposed change

1. Be more granular about which input fields should block dialog if focused. Fixes a bug where toggle buttons (which are inputs of type "checkbox") will block dialog launching if just clicked.
2. Block dialog from launching on mobile devices (using detection code from http://detectmobilebrowsers.com/). Fixes an issue where iOS users currently in template / call service data field / automation editor fields will launch the dialog if they type e or c.
