Issue 1123

📔 Objective

Some users use Text Replacements in order to quickly fill out their email or common usernames in various forms. However, the Username field on the Add/Edit Login screen does not allow for doing Text Replacement, because autocorrect has been turned off on the field, and with the .default keyboard turning off autocomplete also turns off Text Replacement. This changes the keyboard for username fields to be an .emailAddress keyboard, which allows for Text Replacement while still keeping autocorrect off; note that this does not mark the field as an email address field, just the keyboard that shows up is one optimized for email entry. As a large number of usernames are themselves emails, this actually improves entry of those as well.
