Staged Trac upgrade, please test

[Sandro Santilli]

We're in the process of upgrading Trac to version 1.6 and would like
to call projects still using it to test it.

The staging url is:

  https://dev.trac.osgeo.org

The ticket to report problems is:

  https://trac.osgeo.org/osgeo/ticket/2822

A number of Trac plugins could not be installed so if they ring
any bell you could focus on testing them. In particular I see
that TracDoxygen is used by both OSSIM and GRASS trac projects.

  TracDoxygen
  TracSectionEditPlugin
  TracTweakTheme
  BasicThemeEditorPlugin

Thanks for testing !
