Title: IPv6 host string support (#385)

I updated host string normalization/denormalization functions to support ipv6 notation (plus related fix for contrib.sync_project). Parser is not very strict, but it works and passes all existing tests plus several new ones. The syntax examples are below:

::1
[::1]:1222
user@2001:db8::1
user@[2001:db8::1]:1222

Works for me on linux and os x, but more testing is certainly required.
