Got the following changes done to the Image Markup Tool for version 6:

• Generated a new schema, removing my old custom code from the ODD file; the only customization is now the SVG element.
• Finalized the markup format for the <rendition> and <appInfo> elements.
• Updated the conversion XSLT files to convert old versions to the new version, and tested them.
• Rewrote the file i/o code in the application itself, to read and write the new formats.
• Updated the template file used to create a new document.
• Updated and tested the docbook import/export XSLT files. These are slightly complicated, because much markup has to be lost, especially from the <teiHeader>, but there's not much we can do about that. The real test will come when I edit the Help files in IMT.
• Cleaned out old schema files, odd files, etc.
• Updated all the tutorial examples and documentation, using this process to debug and tweak the conversion code.
• Updated the Web View XSLT code, and tested it.
• Updated the installer info.
