changes to our default master: 1) Making it take a doc_type property so that packages can choose for example to change from 4.01 transitional (default) to XHTML 1.0 2) Checking that the default master validates as both 4.01 transitional and XHTML 1.0 strict 3) indenting the the html more properly
changing title of the default start page from Contratulations to ad_system_name. Seems more reasonable given that far from everybody replaces the start page immediately.
Changed a minor bug regarding the definition of user_tab_comments, bumpedto 4.6.3 and added an upgrade script (we may not release a 4.6.3 but if wedo, we're ready!)
