feat(android): add maxImages and pathOnly to openPhotoGallery

[m1ga]

• adding maxImages: max amount of images to select. Use in combination with allowMultiple
• adding pathOnly: won't include the blob in the returned data
• add the path to the returned object

Note: EXTRA_PICK_IMAGES_MAX only works with new Intent(MediaStore.ACTION_PICK_IMAGES) so I have to recreate galleryIntent = new TiIntentWrapper(new Intent(MediaStore.ACTION_PICK_IMAGES));

Test:

var win = Ti.UI.createWindow();
var img = Ti.UI.createImageView();
win.add(img);
win.open();

win.addEventListener("click", function() {
    Ti.Media.openPhotoGallery({
        mediaTypes: [Titanium.Media.MEDIA_TYPE_PHOTO],
        allowMultiple: true,    // test it with and without
        maxImages: 3,
        pathOnly: true,
        success: function(e) {
            if (e.images) {
                for (var i = 0; i < e.images.length; ++i) {
                    // no blob data
                    console.log(e.images[i])
                }
                img.image = e.images[0].path;
            } else {
                // no blob data
                console.log(e)
                img.image = e.path;
            }
        },
        error: function(e) {
            alert('error opening image: ' + e);
        }
    });
})

• click the window and try to select more than 3 images
• change allowMultiple to false and test pathOnly values

@hansemannn : I'm still testing it a bit but it will just give you:

{
 cropRect: { x: 0, width: 1080, y: 0, height: 2400 },
 path: 'file:///sdcard/.transforms/synthetic/picker_get_content/0/com.android.providers.media.photopicker/media/1000043692.png',
 code: 0,
 success: true,
 x: 0,
 width: 1080,
 y: 0,
 mediaType: 'public.image',
 height: 2400
}

as a result if you set pathOnly: true. Can be used in combination with or without allowMultiple and maxImages. So theoretically you can replace the external image picker module.

Also added the multi image picker to Kitchensink: https://github.com/tidev/kitchensink-v2/pull/69 to test it.

Yes, ready for review! I've tested it in an existing app without the new properties and that works as before. So no issues for existing apps and you can enable pathOnly: true to get the new features (no blobs)
