Release/14.1.0 - Extension Data

[colin969]

A fairly large update to allow extensions to work with their own data for games.

May be in this state for a while as it matures and docs get written.

Extensions can now:

• Save arbitrary JSON data on a per game basis
• Add searchable keys which work in search text parsing for top level JSON members in their data (String, number and boolean comparisons)
• Add indexed keys for top level JSON members in their data
• Remove, replace and re-order most Game sidebar components
• Create their own Game sidebar components and add them to the sidebar display settings
