Added functionnalities to IOS

[benjaminhorner]

I added (in IOS only, sorry) the following features.

• method to draw an itinerary passing options (should the starting point be the user’s current position ? should the route be calculated for car or walk ? …)
• method to animate the MKView (height, width, left, right…) within the UIWebView (the holder of the Cordova/Phonegap app). I needed it to slide-in my map ;-)

I also added other methods, but mostly fo my own needs :

• method to add inner shadows (my design needed it)
• method to add a close button
