Gem proportions and Design Report metadata

Translations

• Updated Traditional Chinese by @bisechen

Add Gem

• Tweak proportions for following cuts:
  • Oval
  • Pear
  • Marquise
• Measure size by gem's side instead of height for Trillion, Trilliant and Heart cuts.
  • Affected tools: Add Gem, Select by Trait, Design Report/Gem Map
• Thanks to Maria Dmitrieva (Мария Дмитриева) for pointing that out.

Add Prongs

• Defaults:
  • Make prongs lower (a bit higher than gem table).
  • Better defaults for fantasy cuts.
  • For round cuts put prongs to the side, for easier gems on curve distribution case.

Design Report

• Include image preview from viewport in report.
• Add metadata list in preferences.
  • Use for authoring (project modeller, designer), date of the report, project ID, etc.
• Metadata entries support limited formatting:
  • {DATE} - writes current date.
  • {FILENAME} - writes project filename without extension.

Measurements

• Naming: Measurements > Additional Entries
• New entry type: Metadata.
• Give user an option to choose either object or collection as a target for measurement.

Measurements/Additional Entries system will be completely rewritten sometime later, allowing to use report templates with predefined fields.
