[WS] New feature: Set for tagname pattern

I was thinking whether Set command could be “enriched” with a pattern tagname (regexp).
Set “^TEMP_.*$” “regexp”
or maybe a new sibling command:
Setregexp “^TEMP_.*$”.
Mp3tag would apply the Set command to all tags with given pattern.
Of course existing Set command would work the same if each single TEMP_ tag is listed and nothing is forgotten.
