Added additional JavaScript API attributes

[eas604]

angular-esri-map only supported a few ESRI JavaScript API attributes by default. I needed to support a few more in a project I'm working on, so I added most of the attributes:

attributionWidth, autoResize, displayGraphicsOnPan, fadeOnZoom, fitExtent, force3DTransforms, logo, maxScale, maxZoom, minScale, minZoom, nav, navigationMode, optimizePanAnimation, resizeDelay, scale, showAttribution, showInfoWindowOnClick, slider, sliderOrientation, sliderPosition, sliderStyle, smartNavigation, wrapAround180

You can see several of these directives in test/additional-attributes.html.

Thanks @eas604!

I've tried these changes locally, and they work well and don't break the existing API.

However, it seems that most of these attributes are only used at map creation time, and therefore it would be better to read them from $attrs instead of having them bound to the isolated scope. For example, see how the map directive checks for an extent.

So, even though it is not our goal to have 1 to 1 parity w/ the JSAPI functionality, I'm inclined to merge this if it's modified to read the map options from $attrs. Would like to hear thoughts from @patrickarlt, @dbouwman, @jabadia, @mpriour as well.

Sounds good to me. I actually originally had the attributes in $attrs, and it won't be a problem to switch.

[eas604]

Attributes have been moved to $attrs. Please let me know if there's anything else I can do.

Nice work @eas604.

Would you mind squashing those commits? (You asked...) Once that's done I'll verify and merge unless I hear any objection from the others.

Thanks!

Squashed! Thanks @tomwayson
