Feature/fee options (#116)

* Fee options api integration. Added basic demo page to make fee options request. Some refactoring to demo pages. Fixed a few namespaces

* Decorate fee options return using the indexer so that it includes a bool specifying if the user has enough of a particular token to pay the fee

* Updated SendTransactionFeeOptionsPage (used in the demo page) such that it sends the transaction with the first FeeOption in the user's wallet. This involved also updating the IWallet interface and implementation

* Increment package version
