schemas/public_.sql: analytical_stem_view: applied data dictionary renamings, using the steps at wiki.vegpath.org/VegBIEN_schema_refactoring#apply-data-dictionary-renamings-to-database

schemas/VegBIEN/VegBIEN data dictionary.xlsx: updated: added "to discuss" column requested by Martha. resized columns to avoid truncating the viewFullOccurrence term names.

schemas/VegBIEN/VegBIEN data dictionary.xlsx: updated: finished populating definitions of terms

web/username_prefix.php: deletion comments: also support strikethrough syntax for clarity: (c_)x@url -> c_x@url

added schemas/DwC/hist symlink to history/ to help fit URLs in the 63-char limit

web/username_prefix.php: insertion comments: documented that the semantic meaning of the [] portion also applies, even though it's not included in the linked term name

schemas/VegBIEN/VegBIEN data dictionary.xlsx: updated: finished populating viewFullOccurrence->analytical_stem_view and analytical_stem_view->viewFullOccurrence mappings

schemas/VegBIEN/VegBIEN data dictionary.xlsx: updated: use new deletion comments (with () ) to indicate portions of external terms whose semantic meaning does not apply to our usage

web/username_prefix.php: added support for deletion comments of the form (c_)x(_d)@url -> c_x_d@url . deletion indicates that the semantic meaning of the () portion does not apply, even though it's included in the linked term name.

web/username_prefix.php: comments: use [] instead of () because in writing, [] denotes insertion, while () (as an editing mark) denotes something to remove
