Fix outstanding issues in TokenScript

[JamesSmartCell]

The following issues need fixing in TokenScript handling:

• Boolean return from Attribute isn't working correctly.
• name and label in token props should represent the blockchain name() and the TokenScript label respectively.
• numeric values do not need to wrapped in quotes unless they are hex.
• boolean attributes should be lowercase true or false without quotes.
• For NFT detail page with TokenScript, any Token View should not replace the default view, it should be added at the bottom (aka Dynamic Attributes).
• Cannot render "token" card correctly in NFTAssetDetailActivity if it contains references. Also functions don't show up.
• Add diagnostics for issue where TS developers aren't resolving symbols correctly (currently the app crashed if symbols weren't resolved).
