status bar and/or status message notification for repository syncing

[Jeff Hammel]

a great deal of hacking (see: source:traclegosscript/anyrelease/traclegos/web.py​ ) was used to accomplish TTW project creation with asynchronous syncing of repositories. While this works well using a MySQL DB, using SQLite is not so good as the database is locked for writing. This prohibits (most of the time) the user from signing in and other interesting actions. While this problem cannot effectively be worked around, it would be at least nice to inform the user of progress. This could be done via a status bar or notification on each request, using the WSGI middleware to write the status message.
