Fix replace FancyURLopener with HTTPBasicAuthHandler

When using username/password on python 3 FancyURLopener prompt_user_passwd is not even tried on http_error_401 and always returns http_error_401
Switching to  HTTPBasicAuthHandler solves this issue.

Note:  HTTPBasicAuthHandler has a known issue on python 2.6.5 where using wrong credentials lead to an infinite recursion
Added a fix based on https://gitorious.org/opensuse/osc/commit/aa2832f52581e9be6a9e620f55834de6f4760692 to prevent this issue
