Button to reorder Mail folders alphabetically

[gtandersen]

Is your feature request related to a problem? Please describe. If Mail folders have been reordered manually and an alphabetic order is once again desired, this needs to be done manually as well.

Describe the solution you'd like A button near the folder list that reorders folders alphabetically (with a confirmation dialog).

This should also include sub-folders.

In addition there could also be an option in a parent folder to sort just the sub-folders of that parent folder alphabetically and this would give fine control.
