fix: added eventbus-1.4.jar

Needed for scijava-common EventService.
WIP: updated scijava-common jar to fix npe

Added a custom scijava-common jar that fixes an NPE when checking
versions from the pom.

Not sure why the npe is thrown at all as the meta-inf looked good, but
this will be fixed before a release of scijava-common is cut.

This jar should be replaced with a release jar eventually.
fix: moved tutorials to ome.scifio package
fix: renamed tutorials to imply ordering
wip: converting scifio services to use priority/params
