Teach route to squeeze slashes

[SokratisVidros]

• Sanitise paths during route declaration and matching
• Add basic error handling during sanitization

That way accidental inbound requests such as http://foo.com//path/to/server will match /path/to/server and be routed successfully.

I understand the intention here, but it should be optional through a flag

Is there a scenario that a developer would want multiple slashes to work?
