Added EMK logic and service

First step of many. This commit prepares the API for the EMK and adds the
basic EMK service which is used by all clients/consumers to access the EMK
data.
Added file transfer service

Added basic file transfer service (internal only right now), which has the
purpose to allow controlled (read-only) access to resource files on the
server.
This will be used later within the clients to access the icon files of the
resources (stored in the EMK data).
Created new widget for displaying of EMK
Apply filtered resources from service

If that fails, we use a fallback method and just apply all resources associated with the operation.
Only consider EMK resources that are active
Updated file transfer service

- Added exposed service for client access.
- Allows for easy transferring of server-side content to client(s). Includes caching for a better performance.
- Added convenient FileTransferServiceClient which provides an efficient interface for client users.
Made widget more informative

Added icon, which is transferred in the background. Also display the friendly name of a resource, if present.
Added new test for verification of "IsActive"
Corrected platform target

Made SettingsService less verbose

Removed some now annoying log messages. They were OK when first introduced, but now, they are no longer necessary and clutter up everything without adding much value. Only log something now if it is important.
