netrender

- Add "Get Result" button after a job has been sent (this calls Animate and fetches the results back as render result buffers)
- Rendering (animate or single frame) without an active job was broken. Note that this launches a new job for each frame (it's impossible in a render engine to know if an animation is being rendered or a single frame only).
