Pattern updates

[omrilotan]

• Adjust the "bot" substring match (issue #229): The substring "bot" should be either a word or a suffix, not in the middle of a string (excluding Cubot).
• Add rest-client Ruby HTTP client
• Add two app patterns to recognise as browsers, not bots

I have decided to not treat "SpringBoot" or "retweet" as bots. They seem to be user agents for handheld devices' applications - these are not considered self-identifying automated tools.

Resolve issue #229 Resolve issue #230 Resolve issue #231 Resolve issue #232

These adjustments will be released with the isbot@4 branches which will become the prominent "latest" version.

Please see migration guide.
