Image Upload needs Auto-Resize

[rootzoll]

At the moment its just possible to add/upload pictures with 1MB max to a task. This should be without limit, because most pictures on users phone are bigger. But on server side the image should be reduced in size before stored to DB to minimize storage and network transfer on delivery later on.

TODOs:

• remove file size limits on app side
• resize image on API / server side (max 400px width) before storage

last one would be best done by pure Java code ... maybe by something like this: http://www.mkyong.com/java/how-to-resize-an-image-in-java/

Some could write a small tool class that can be used within REST-API code later on.

the app now allows upload of images up to 10MB ... next step would be to make server side resize
