brute-force should check deep level

[blshkv]

I facing a case (https://github.com/wiire/pixiewps/releases) where the version changed from 1.1 to 1.2.2 and the tool is unable to detect it.

btw, it must be a better way of checking it. I'm sure github provides an API which allows to get the latest version. Something like https://developer.github.com/v3/repos/releases/ this one perhaps?

GET /repos/:owner/:repo/releases
