Fast s r

Builds off the work of @santagada to speed up search-replace. Uses a regex select to see if serialized data is present, and if so runs the fast replace on the row. If not, runs the normal search-replace which replaces the rows in a serialize-safe way.
"Fast Replace" only means something in a specific context. Let's change the column header to "Type", and have our types be "PHP" or "SQL"
