Expanding contract interfaces template, filled out for resolver page

[serenae-fansubs]

Generic interface templating moved to interfaces.tsx. Each contract/interface page just needs to call interfaceDetails.

Added ContractParameter, where both inputs and outputs can be specified. Each parameter/result can have its own specific description.

The seeMore field will automatically have EIP/ENSIP keys turned into links.

A new examples field can be used to show usage examples for methods.

And other small tweaks.
