1.0.0-rc.3: Browser enhancements

Changes from v1.0.0-rc.2

Enhancements

• Showing list of primitives (#143).
• Fixed misalignment of data cells and header cells (#151) by adding visual cues that more data exists (#107) instead of adding permanent scrollbars.
• Changes to the way lists and object references are displayed (#126) - making them more language independent.
• Revisiting the way list of object references are shown in the sidebar (#16).

Internal

• Now releasing from another branch than master, to prevent unintended continuous releases.
• It's built with realm version 2.0.0-rc22 and tested with realm-object-server version 2.0.0-rc.5.
