* Do not include oldIdx in Select change event
I included it due to confusion about the variable names in the Change Notetype components.
* Remove redundant on:change listener from NotetypeSelector
* Use Select component in Change Notetype MapperRow (again)
* Remove redundant --cols and --col-size definitions
Bootstrap divides rows into columns of equal width by default.
* Add highlight to active DropdownItem
* Remove bootstrap dropdown item styling
* Fix JS error on dropdown accept action
cause: When closing the dropdown, buttonRef was removed before the callback in setTimeout was run.
