[RELEASE CANDIDATE] v3.0.0rc5

Probably, this will be the last Release Candidate. I do not have a lot to add or fix now, so this is now practically ready to use.

Changes

• Added newer documentation
• Config options updated:
  • time_format removed
  • time_language now refers to a language subtag, like "en-us" or "ja"
  • icon_theme allows to specify the cursor theme to use
• mock.js updated
• Vendors updated:
  • material-icons added
  • js-cookie updated
  • fontawesome updated
  • jQuery removed
  • moment.js removed
  • Bootstrap removed
• Transifex translations removed, as they are not compatible and not mantained.
