F4901: implement 'delete split files' if primary file is deleted (record) or exchanged against a new one.

# Conflicts:
#	extension/Documentation/Manual.rst

F4901: implement split with 'convert' (jpeg). Refactor chmod(), unlink(), rename(), rmdir(), copy() to use by QFQ version which throws an exception.

thumbnail: empty path filename no ignored. Instead of throwing an exception, it returns just nothing. This is the same behaviour as building links - no definition means 'no link', and not 'error'.

QFQ now recommends ImageMagick instead of GraphicsMagic, due to much better 'convert' quality by converting 'svg' images.
