Consume Papyrus Compare release in UMLLight

[planger]

Once EMF Compare 2018-12 is released, we should make an official release of Papyrus Compare that is based on EMF Compare 2018-12 and consume that in UMLLight.

EMF Compare 2018-12 will be made available later today, hopefully.

Unfortunately, there was an API break in EGit 5.2 (released 2018-12 as well), which breaks the EMF/Papyrus Compare tests. So we'll likely need to restrict compatibility of the to-be-released Papyrus Compare to https://download.eclipse.org/egit/updates-5.1.3.

I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=543297 to track this issue.

The PapyrusCompare nightly build has been updated to 2018-12 and is now ready to be promoted to an integration build. We should do a last test round and then publish the ingratiation build as 2018-12 release.

After that is done, the only remaining things are

1. to switch the release of Papyrus UMLLight to Papyrus Compare
2. update the papyrus compare wiki page that there is a release for 2018-12
   Thanks!

Great, thanks @tortmayr!

@cdamus Can you please take over making the integration release for Papyrus Compare? I'd then do another test run with it and then I think we are ready to make the release of Papyrus Compare and make the change in UMLLight to consume it.

@planger The 0.7.0-N20190124-192745 build is now published as 0.7.0-I20190124-192745 in the 0.7.0 integration builds.

@planger The 0.7.0-N20190124-192745 build is now published as 0.7.0-I20190124-192745 in the 0.7.0 integration builds.

Thanks @cdamus! Works very well! The current integration build is ready to be promoted from my point of view. Overall there are only the following things to do:

• Promote current I build as release (@cdamus)
• Use release update site URL in Papyrus Compare (@planger -- I have a branch already prepared on my local machine, which consumes the current I build and adds the recommended settings in the plugins_customization.ini; so this would just have to be changed to the release update site) To be reviewed and tested by @tortmayr once pushed
• Update https://wiki.eclipse.org/Papyrus_Compare to mention the release (@tortmayr and @planger )
