Re-structured the code completely to use modules.

This will be better in the long run for code portability as we now use a base.rb file to track overall structure and leave a large portion of the logic to the individual files. Also introduced the `::QuoraWebDriver` namespace to clean up more code. We don't want to clutter that shit.

Merge pull request #5 from kratsg/restructuredCodeUsingModules

Modules and namespacing, bump to 0.1.3. This should also close features #1 #2.
