WIP: Generating transaction on Send tab (Pt 1) (#100)
* Generating transaction ,placing into read only textareas. * Fix async wallet getAddress cases. * Chain id from network * remove leftover console log * Check balance before generating transaction. * Translate error msgs, check for invalid address. * Errors for gas limit and gas price issues.
