- modifies oc_tables_share structure with two columns, token and password
- adds ShareOCSController with a route to create link shares
- adds a PageController front route to display the link share
- adds a ApiPublicColumnsController to retrieve columns for public
  links. It was not added to the existing ApiColumnsController, as it
  requires the userId of the logged-in user and I did not want to weaken
  this detail.
- adds an abstract controller for columns with shared functionality and
  make ApiColumnsController extend it.
- adds a PublicRowOCSController for retrieving rows through link shares
- adds a ShareToken value object
- adds a ShareControlMiddleware for share token and existance
  validation. It comes with the AssertShareToken attribute.
- extends Share entity with ShareToken and Password properties
- extends ShareMapper to find a share by the share token
- extends ShareService with a method to easily create link shares
- extends ResponseDefinitions with TablesPublicRow and
  TablesPublicColumn specs. Essentially tableIDs are not exposed and
  also user ids in lastEditBy and createdBy are not disclosed.
- extends RowService and ColumnService with methods to return such ^
  formatted result arrays.
- extends OpenAPI spec
