Added the ability to clear fields with an X that displays in fields once
they are no longer empty. Added a request to change focus to the "Pickup
To Location" when user selected a location in the "Pickup From Location
Field". Attempted at a fix of a bug I noticed in the clear signature
field.
Commited/Pushed so Patil can grab and merge with my (brianH) latest
code. Note: Bugs still exist in Clearing the Signature.
