Fiddles are now stored in the filesystem so they can be preserved across page reloads, but also so that contracts deployed via fiddles can have their source code shown.
Fiddles deployed as contracts now fully work with existing contract list UI and functionality. Fiddle deployed contracts are listed in a separate section in the UI.
Current limitation is that only single contracts per file are supported. If the fiddle contains multiple contracts, it’s currently not supported.
Fixed browser errors caused by tabler (bodyItems and headerItems complaints) as well as staticContext issues caused by using withRoute(NavLink)

Removed extra space after function in solidity compiler (as requested).
Removed the compile contract event from the solidity compiler (as requested).
Handling of fatal api error in the UI.
Changed fiddle action to the one created with `createRequestTypes`.
