Update Revision Display

[#1]

Hello,

It is at the moment quite cumbersome to look and compare revision within Launch.
I feel that the problem lies in the following element :
- Revisions are all numbered and starting some time, you are never sure which one is the live one.
- Some revisions version exists but where never published live

The idea(s) would be to have an information next to the revision version in order to identify:

- The version that is live

- The version which is in a Library (should be the highest number but not always)

So you can easily compare :
- Version X vs Live version- Version in a Library vs Live Version

Also, it would be great to clean the version / revision that were never set live at any point.
When a revision is build live, look at all the previous revision and delete all the one that were between 2 live versions.
It would help clean the versioning.
