Optionally allow text inputs from popup window

[An-anonymous-coder]

Websites are able to fingerprint you based on your typing style while you are typing. The solution many present is to first type into a text editor, then paste it into the field you want to type in. Vanadium could automate this by having an optional toggle to show a text entry popup window each time a text field is focused, where users can type their message into the popup window and have it automatically get pasted into the text field when the user is finished.
