Log Message: ----------- Markdown: Allow exporting Markdown as HTML (#502)
* Markdown: Allow exporting Markdown as HTML
Add a Tools menu item "Export Markdown as HTML" to allow saving of the rendered HTML to disk instead of just the live preview.
Closes #497
* Markdown: improve Export to HTML feature
* Use the document's filename as the basis for the new HTML filename. * Properly setup the initial directory and suggested filename in the file chooser. * Re-run the file chooser after showing error message if saving fails.
