0.7.1

Fixed

• SanctoraleFactory.load_with_parents crashing on files without metadata
• Sanctorale#update prohibiting application of a particular calendar which moves s celebration contained in the calendar being updated to an earlier date (as exemplified by the bundled calendar of diocese of Litoměřice, Czech Republic: on calendarium-romanum 0.7.0 CalendariumRomanum::Data['czech-litomerice-cs'].load_with_parents raises ArgumentError complaining about non-unique celebration symbols)
• broken links in YARD documentation (due to files missing in the gem archive and basename clashes)

Changed

• if Sanctorale#update raises ArgumentError complaining about non-unique celebration symbols, the updated Sanctorale instance is left in an inconsistent internal state (more than one occurrence of at least one celebration symbol)
• some additional non-code files (mostly for YARD documentation) included in the gem archive
