[ZWeb] SWRelease update version-strings

[Michael Haubenwallner]

Zope.orgs 'swpackage_view' (default view) takes all releases of a 
SWPackage, reverse sorts on the release-version string and takes the 
first element of the list for the 'Latest Release: ' display too.

For all of you that need to change/update the version-string of a 
SWRelease without changing the objects modification date, i created the 
'swrelease_updateVersionString_form' (use it instead of the default edit 
action: 'swrelease_edit_form').


Hope that helps with creating better release displays
Michael
