Remove all sezpoz references

sezpoz is no longer being used for annotation processing, so there is no
need any more to refer to the sezpoz jar.

Fixes an annoying bug in that the m2e profile added the sezpoz depenency
explicitly, which could not be resolved (as sezpoz.version no longer is
defined).
Update Fix_Updater.js

Thanks to bin/updater-jar-urls.bsh.

Merge remote-tracking branch 'origin/remove-sezpoz'

The Fix_Updater.js script has been adjusted differently in the previous
commit, hence it conflicted with the merged branch.

Thanks Mark Hiner!
