Github link validation - prep for user input

[courte]

This code prepares to allow users to input a github link when adding new projects to the platform.

• Adds a module to:
  • match the url to github repo format
  • adjust the link to match githubs preferred format (minimizing 301 responses)
  • check validity of input (Is the link real?)
  • return a hash of the organization/user & repo names, parsed from the url
• Adds some tests for said module

Using the url https://github.com/CodeMontageHQ/codemontage/pull/269 works when it shouldn't

get_github_details('https://github.com/CodeMontageHQ/codemontage/pull/269')
 => {:github_org=>"CodeMontageHQ/codemontage/pull", :github_repo=>"269"}

Nice example, @acrogenesis! Thank you.

Thanks for the heads up, @acrogenesis! I've added some commits that (a) add your example to our existing specs & (b) account for word chars & dashes instead of any non-whitespace character (which was clearly far too broad).

The regex is ugly but (currently, maybe, fingers-crossed) gets the job done.

Simpler, cuter solution at #286.
