Improved data retrieval in GitHubData class

[rroyGit]

Once GitHubThread is initiated, a new thread is started - responsible for checking if cache is valid.
Locks are used to handle the two threads, http call starts running asap after cache thread has finished. Http thread maintains cache property set by the owner - no http connection calls if cache is last modified within the last 10 days.
In case http thread runs before cache thread, http thread checks if cache thread is alive - if yes, http thread waits until cache thread successfully finished.

This should solve the loading lag if the cause was making http requests.
Let me know how it goes for you.

Oh boy, I've... never actually seen anyone use a Semaphore before. This looks good. I shall test.

Upon initial inspection, it appears that doHttpConnection() is never called, even when the cache isn't present, and so nothing is passed to the init method and... nothing loads. Not loading anything has definitely sped up the loading speed a lot though, so great work!

Lol. I'm currently putting in an excessive amount of log statements to see if I can figure out where it's going wrong.

Found it. It is not quite as speedy now, but definitely an improvement over what was there before. Thank you for contributing!
