Fix #6918 Allow aliases with capital letters in rules
Expand the types of Form_IpAddress so that the caller can specify exactly what combination of IPv4, IPv6 address and alias is allowed for the field. Set the appropriate input pattern and hover help text. Only toLowercase() the entered value if it has a ":" in it - i.e. it looks like it is intended to be an IPv6 address (rather than an IPv4 or an alias name).
