Added integration with Ledger devices via the LTO Ledger App
Added necessary libraries to make that happen
Only transfer transactions are available, as further development needs to be done on the Ledger app to support other transaction types (see issue #4)
Because of that, a popup has been added to the pages of the transaction types that are not supported by Ledger, so that the user knows about it
Added script for server, where the bridge is mocked (data is on /mock-data/lto-bridge.json). json-server is used to supply an endpoint on localhost with the mocked data from the Bridge, since testnet bridge is not reliable (there are CORS issues, as well as it's not maintained).
Under polyfills.ts some workarounds were added, result of adding the Ledger-related libraries as dependencies
