* Add aliased W3C routes
* Implement getTimeouts command
* getTimeouts returns an object containing all the timeouts and their values as key-value pairings
* Added routeHandler too
* Added w3c routes
* Remember protocol requested in createSession
* Also renamed 'processCaps' to 'processCapabilities'
* Checks the parameters in 'createSession' and determines if it's W3C or MJSONWP
* Add W3C error format
* Add W3C status codes to errors
* When deciding error format to return in mjsonwp.js, check format and then return eitherJSONWP or W3C format
* allow both 'value' and 'text' params for setValue
this introduces a 'makeArgs' option for the spec which allows handling of more complex scenarios.
* clarify some variable names and add fuller commentary
* Update hash
* Add validateCapabilities and parseCapabilities
* Added merge capabilities
* Moved capabilities into it's own file
* Added capabilities as a possible required param
* Can pass desiredCapabilities or capabilities into createSession
* Remove 'required' desiredCapabilities
* desiredCapabilities isn't required any more because we can provide capabilities as well
* Will need to update validation logic in 'driver.createSession' to do the validation there instead
* Code cleanup
* Skip presence constraint in parseCapabilities
* We don't need to check that items are present until after we've formed the matched capabilities
* Added validation function to routes
* Function 'validate' takes params as an arg and then returns a message if the validation fails
* Uses this to validate that either "capabilities" or "desiredCapabilities" was provided
* Renamed capabilities to caps
* Move caps required validator from process to parse
* Removed InvalidParametersError
* Update BadParametersError so that if a message is added as the 3rd argument it shows a different error message
* Made validation re-usable
ProxyRequestError will be thrown for all unsuccessfull proxy requests, ProxyRequestError will contain the actual error route cause information(`jsonwp`)
