Add includeBoundaries option

[Mottie]

Restored previous behavior:

const ipRegex = require('ip-regex');

// Contains an IP address?
ipRegex().test('192.168.0.2000000000');
//=> true

// Matches an IP address
'192.168.0.2000000000'.match(ipRegex());
//=> '192.168.0.200'

Added includeBoundaries option:

const ipRegex = require('ip-regex');

// Contains an IP address?
ipRegex({includeBoundaries: true}).test('192.168.0.2000000000');
//=> false

// Matches an IP address?
'192.168.0.2000000000'.match(ipRegex({includeBoundaries: true}));
//=> null

Sorry about the long delay. This one got lost in my tabs.
