Return MobileElement directly from AppiumDriver.findElement?() and findElements?() methods

[prattpratt]

I found out that we can make AppiumDriver to convert element Json representation directly to MobileElement rather than RemoteWebElement. So we don't need to wrap RemoteWebElement inside MobileElement but just use MobileElement as a rightful successor of RemoteWebElement.

Instead of:

MobileElement el1 = new MobileElement((RemoteWebElement)driver.findElementByAndroidUIAutomator("resourceId(\"android:id/content\")"), driver);

we can write down it in more simple way (as we used to) :

MobileElement el1 = (MobileElement) driver.findElementByAndroidUIAutomator("resourceId(\"android:id/content\")");

and also we can continue searching to find a child element under el1 (means use any methods available inside MobileElement class):

MobileElement el2 = (MobileElement) el1.findElementByAndroidUIAutomator("text(\"Accessibility\")");

Awesome! I didn't know about the setElementConverter function.
Thanks for updating that, AND the MobileCapabilities enums AND some tests.

I'm going to run all the tests, and add the methods described in #51 #55 #56 and publish a new version ^.^

No problem!) Will be waiting for a new release.
