Localhost check doesn't work correctly with IPV6 server name '::1' - results in Uncaught exception 'EpiTwitterException'

[alex-gonzalez]

When using the library on my local machine with IPV6 the check for localhost in EpiOAuth isn't triggered because $_SERVER['SERVER_ADDR'] is '::1'

I changed line 171 in EpiOAuth from:
if(isset($_SERVER ['SERVER_ADDR']) && !empty($_SERVER['SERVER_ADDR']) && $_SERVER['SERVER_ADDR'] != '127.0.0.1')

to:
if(isset($_SERVER ['SERVER_ADDR']) && !empty($_SERVER['SERVER_ADDR']) && $_SERVER['SERVER_ADDR'] != '127.0.0.1' && $_SERVER['SERVER_ADDR'] != '::1')

This may be useful to other developers working on their local machine and getting this exception.

Got the same problem here, localhost with IPv6. I've tried the proposed solution and it works. Please accept the PR.
