When a Web uses one of the Markdown Text Filters, and you export
all the pages as a zip file, you'd like the MathML and SVG to
render when the pages are viewed locally. This means saving them
with a .xhtml extension. Users of non-XHTML-capable browsers or
Textile users should still get .html files.
Links to a published web should be to the 'publish' action, not to the
'show' action. Previously, the published status of the source, not the target
was used.
Also, correct display of the Navigation Links for the 'published' action.
The file upload dialog asks for a description of the image or file to be uploaded. Use this as the default alt-text for the image and as a title attribute for a file link.
