"First revision" setting is overloaded.

[mpotter@…]

The "First revision" setting on the "Manage Build Configurations" recipe page, "Repository Mapping" section is overloaded. This setting effects:

• How far back to build, if the "Manage Build Master" page "Build all revisions" setting is set.
• How far back to chart lint, test, and coverage results.
• How far back build results can be found in the user-interface. Even though the older results are still available, but only through direct URLs.

In a system that has been running for a long while, where "Build all revisions" setting is set, a new platform is added to an existing recipe. System will thus try to build this new target all the way back to the "First revision" setting, however all these build attempts, but for the most recent revisions, will fail. However, setting "First revision" to a current revision will also reset the charts and make the older build results inaccessible.
