schemas/VegCore/VegCore.ERD.mwb: removed occurrence table, because it's really a synonym for taxon_occurrence ("specimen, observation, etc." <http://rs.tdwg.org/dwc/terms/#Occurrence&gt;)

schemas/VegCore/VegCore.ERD.mwb: added labels for the left and right halves (event and occurrence). rearranged tables to help separate event- and occurrence-related tables.

schemas/VegCore/VegCore.ERD.mwb: rearranged to leave more space for location_observation, and to put all event-related fields on the left and occurrence-related fields on the left

web/.htaccess: parse dotpath in query string: heuristically detect query strings that don't contain dotpaths (such as mod_autoindex sort conditions), rather than always interpreting the part before the first & as the dotpath. now, the part before the first & will be interpreted as a dotpath if it has a . before any = . (query param names containing . are rare, so this usually works correctly.) note that you can always prepend . to force a dotpath, or & to force a query param.

web/dotpath.php: remove any . prefix which forces interpretation as a dotpath

schemas/VegCore/VegCore.ERD.mwb: taxon_concept: renamed source to according_to

schemas/VegCore/VegCore.ERD.mwb: removed no longer used images from zip archive using `zip -d`. this needs to be done every time an image is deleted from the diagram to remove it from the archive (and reclaim the unused space, since `zip -d` will also shrink the archive). note that you can't just expand and re-zip the files, because there is a header of some sort that indicates to MySQL Workbench that it's a valid .mwb file.

bugfix: schemas/VegCore/VegCore.ERD.mwb: also fixed inheritance relationships to the record table to be 1:1 (by search-and-replacing and then updating document.mwb.xml in the .mwb zip archive using `zip -u`). added separate legend for relationships and connector styles, which now uses example tables instead of screenshot images to ensure accurate sizing at all ERD zoom levels.

bugfix: schemas/VegCore/VegCore.ERD.mwb: fixed inheritance relationships to be 1:1 with optional participation by the derived table, rather than the incorrect 1:many relationshipwhich MySQL Workbench defaults to. (in OOP, each derived instance has its own instance of the base class, because it is a separate object.)

web/**/.htaccess: When there is no external redirect for the directory without the trailing /, instead auto-add the trailing / to ensure mod_autoindex relative links work properly. This must be done manually because the top-level .htaccess will not auto-add the trailing / if the dir has an .htaccess file (to allow the custom external redirects). There are actually only two .htaccess files that this applies to (web/.phpPgAdmin/.htaccess, .phpMyAdmin/.htaccess), indicating that dirs which have any kind of virtual paths (redirects) almost always have a "root" redirect when there is no specific subpath. This root redirect is intended to link to the datasource's own index of its available resources, e.g. the list of tables for a database source.
