Merge pull request #2041 from gchq/octal-ip-addresses

Addresses bug report #2008
Added explicit support for octal IP addresses.
Changed approach to IPv4 regex to be string manipulation generated.
Added some unit tests for IP address parsing - probably not full coverage.
Added lookahead and lookbehind tricks to resolve warned issue that 1.2.3.256 would still be extracted as 1.2.3.25. Now only accepts valid IP addresses. Warning replaced with clause about infinite length dotted decimal forms.
