* Add feature: Read and write all options from / to registry, using some existing CSV-options
* Fix bug: Correct escaping for db, table, columns, values for terminator, etc.
* Style change: Drop superflous checkboxes from checkbox/edit pairs to save clicks. Checking for empty edits has the same effect.
* Style change: Don't convert backslashes in filename to slashes. No need to take care of escaping, esc() does that better.
