Update patator.py

HI, this a bit more descriptive, when get xxx/unexpected HTTP response, this show what host is "down", and this avoid need to recheck server with curl/wget/etc

for example now when connection to server fail, will get this mesg
06:31:11 patator    FAIL - xxx  17:-1          0.000 | admin                              |    10 | Failed to connect

btw thanks for great tool :)
best regards
