Added option for user to enter info if none found

If .xsend is not found, the user can choose to enter their login information in the program. I rearranged the order that some of the file.readlines() take place. Also misc fixes to spacing etc.
Added else statment If user info is not found

If the user information is not found and the user enters something other than yes or no, the program exits.
