Added Jonker Volgenant Algorithm to TrackMate
library updates (imglib, scifio, scijava)
library update - fixed classpath settings and dependencies (forgot to add the newest scifio-bf-compat to plugin dependencies)
updated io classpath
libs for knip.io rebuild and re-added, after removing all libs (to make sure that removed dependencies are also removed from the classpath)
Fixed minor bug in tracking

- more major than minor, but fixed anyway. positions were calculated
wrongly
added ome-xml to export in knip.io
Print stack trace if something goes horribly wrong in ReadFileImgTable.
Increase progress count only when the next file is read (and not the next series).
Re-initialise reader in ScifioImgSource when its metadata has been set to null.

The metadata of a reader is set to null after an image (one series) has been read (the ImgOpener closes the reader).
Bug 5158. Fixed

Use Cross Platform Look&Feel for the JFileChooser instead of the
default one.
