[Aleph rest-dlf connector] Imported XMLBuilder from https://github.com/jmurty/java-xmlbuilder & used it to create valid XML POST HTTP request to update user on API's "patron->address" level
Also modified webapp appearance a bit & added button to easily insert newly created NCIP XML request based on User Id, using UpdateUserService to debug rest-dlf part easily
Also implemented Problem crafting after UpdateUser have failed.
