Merge cc3e6d45ba into 260eedf8c4

The is_domain function was being called in ssl_cert_issue() but was never
defined in x-ui.sh, causing 'Invalid domain format' errors for valid domains.

Added is_ipv4, is_ipv6, is_ip, and is_domain helper functions to match
the definitions in install.sh and update.sh.
