Category and Group icons

[inghamn]

The open311 clients we develop want to have icons shown for each Category and Group (Open311 Services). The challenge is that the clients have no knowledge of what the groups and services are; so, creating icons for the services and groups is not something that can be committed as part of the source code of the ureport-client application.

The Open311 specification does not support declaring icons for each service. So, this would be a custom uReport thing. Since the new ureport-client application is not attempting to be a pure Open311 client, this should be possible.

uReport categories and groups should have a place to upload an image file. This image needs to be hosted at a well known URL for the category and group.

Our current client in development only wants to have icons for the Groups. We could get by with only implementing image uploads for groups.
