-Fix code Migration of kotlin:

annotationProcessor  to kapt
-In screen IntroActivity: Show toast when there is not connection with server
-In screen Create Seed: Code to interface when error ocurs in WebSocketThread and GrapheneApiGenerator
-Fixes to class WebSocketThread for error Report to user
-Fixes to class BitsharesCryptoNetVerifier for error Report to user
-Fixes to class CryptoNetVerifier for error Report to user
-Fixes to class CryptoNetManager for error Report to user
-In the IntroScreen: If there is not server connection show a simple user message of that
-Create class ToastIt in kotlin
-Create class NetworkUtility in kotlin
-In the IntroScreen: When the user Press button “create account” it has to validate connection to server to continue
-In the IntroScreen: When the user Press button “Import account” it has to validate connection to server to continue
