Merge pull request #355 from bob-v-t/master

Removed scroll bars from Android driver's WebView in order to allow automated screenshot comparison
bumping selenium dependency to version 2.41
Added support to switch context between native and webview.
cleanup in the capabilities
Moving AndroidManifest.xml in selendroid-standalone into test resources.

This way, when importing Selendroid into an IDE,
it doesn't consider the Manifest as descriptor
of an App.
Changed handling of switchContext(WEBVIEW_ID) by normalising the input.

Now, commands to switch to "WEBVIEW" will be interpreted as
"WEBVIEW_0".
Also, switchContext(INVALID_HANDLE) will throw an exception.

Fixes #362

NOTE: In case of INVALID_HANDLE the exception thrown is "NoSuchWindow".
In the future this will have to change to "NoSuchContext".
