Removed commented out code
Added typhoeus as a development dependency and switched out double-quotes for single-quotes where applicable
Updated browser_spec to use correct internet explorer incantation
Split the launcher spec into two different files -- one for local and another for grid. Also added the standalone server to the spec directory and made it auto-launch for the tests.
Switched the HEAD request for a GET request for the Selenium Server status check to work
Replaced 'grid' with 'remote' both for execution, tests, and documentation. Specifying 'grid' will no longer work. This was done since 'grid' is a form of a remote instance.
Updated gemspec to exclude vendor directory of tests (so large files that are test dependencies don't end up bloating the gem).
