Subject: [PATCH] Fix #3511 Add hyperlinks to EntryPreviewWidget notes field

This change adds support for hyperlinks in the notes field of the EntryPreviewWidget. This is done by enabling the `openExternalLinks` property of `QLabel`, and modifying the value of the content of this field so that links are wrapped
with `<a>` tags.

Links are assumed to use the format: `protocol://path`, since assumptions cannot/shoudn't be made about the specific format of a link. The text of the label uses the modified notes value.
