minor tweaks to pyrex

updated pyrex workbook

fixed so it really should work now with MultiPoint shape files
(although I haven't found one to test with).

added support for Point and MultiPoint shapes in shapefiles
(from Erik Andersen's patch tracker submission).

add initial support for reading shapefiles with Point shapes.
(from patch by Erik Andersen on the patch tracker)

let widgets.Cursor initialize to the lower x and y bounds
rather than 0,0, which can cause havoc for dates and other
transforms
