Add git-describe logic to ant/common.xml

Two calls are made to git-describe in order to detect
whether this is an exact or an inexact match for a tag.
The release.version property is then built up from the
parsed tag and should be used as the basis for all versions.
Move all 4.5-DEV build.properties to use release.version
Also change ome-xml/bin/build.properties

Unclear why this exists!
Also change scifio-devel and scifio-tools

Unclear why these were set to different values.
Use @release.version@ in FormatTools
Strip [exec] Result: 128 from output
Allow omero.version override
Merge pull request #627 from joshmoore/9639-tag-describe
