Use alternate pattern match during field changes

Browse source 
When a user renames or deletes a field, Anki tries to go through the
user's templates to substitute occurrences of that field name with its
new name or remove the field.

However, if the user has multiple Mustache placeholders on a single
line, this does not work as intended because the leading (.*) capture
group grabs the text in-between the two (or more) Mustache placeholders.

Examples:

    {{#Flag}}
        ...
    {{/Flag}}{{^Flag}}
        ...
    {{/Flag}}

or

    {{Front}} {{#Flag}}...{{/Flag}}

or

    {{Front}} Hello. {{Victim}}
