Plug-ins: only File › Open lists importers' files, and imported art at the canvas edge keeps an editable artboard

Browse Source 
New from Template, Load Character/Paragraph/All Styles, Recolor's Other
Library… and the library panels' Other Library… read files with the
built-in readers, so their open dialogs now use builtin_open_filters(),
which leaves out the extensions only importer plug-ins read. File › Open
keeps open_filters() with the importers' files.

The artboard of a document an importer opens is now kept within
±4,000,000 pt. Art at the edge (a zero-width path at x = 4,000,000, or a
stroke past the edge) gave an artboard beyond it, and every later edit
of the document was rejected.
