Loading files via URI string fails

[saschpe]

Is your feature request related to a problem? Please describe.
ImageView.load("file:///data/user/0/foo/cache/1.jpg") fails with

 java.lang.IllegalArgumentException: Expected URL scheme 'http' or 'https' but was 'file'
        at okhttp3.HttpUrl$Builder.parse(HttpUrl.java:1328)

because it is directly handed down to OkHttp3.

Describe the solution you'd like
A check if the Uri starts with *file:// could map to load(file: File) instead.

Tracking support for this here: #24

The current workaround is to use ImageView.load(Uri.parse("file:///data/user/0/foo/cache/1.jpg")). The fix for this will likely make it into 0.7.0.
