Added ability to save an image of the graph, fixed graphing so that timing is relative to the start of the capture (this makes viewing one capture after another with the same graphs much easier). Fixed rescale when importing a new file (no longer rescales).

The bottom line is that it'll be a lot easier to work with graphing of multiple files now.
