Out of memory in Media Viewer

[kefir-]

This seems related to the issues noted in #154. I've added an E01 image of a 16GB memory stick I had floating around, and on that stick were about 150 pictures from a digital camera. Browsing the content of the memory stick with autopsy, it works for a little while, but then the pictures suddenly stop showing and I only get a black screen.

Looking at Autopsy's messages.log I see this when I try to view a picture:

JNA: Callback org.gstreamer.elements.BaseSink$2@19b713d threw the following exception:
java.lang.OutOfMemoryError: Java heap space
JNA: Callback org.gstreamer.elements.BaseSink$1@5a3a8a threw the following exception:

I closed Autopsy after ingest was done, restarted, and after that I could view 7 or 8 images before they started failing again. Here's the output in messages.log when they failed:

We should retest this with next release which fixes some memory leaks

Note: this is MediaViewer / gstreamer issue, resulting in heap issue only (not native) when trying to render an image.

Improved image loading in MediaView and Thumbnail View. It is faster and handles large images better.
It may fail for really huge images (NASA - like), but with better error handling.
