Modified calculate_md5_of_dir
Created Users(Resource) class with delete_user method.
[ ] Signup (POST)
[ ] Create user (PUT)
[X] Delete user (DELETE)
[ ] Get user unfo (GET)
server message consistency
in Users.delete, the username is not taken from auth but is passed as argument (as the API says)
class "Users" moved below old create_user function
Bugfix: <username> was not taken from url
'test_delete_user' test case added
deleting other users is now forbidden
if <username> is not in userdata and I'm logged, it's not a 404,
it's an error of coding. So I removed this if.
