Minor clean-up and reindent

TracBrowser: folders can now be expanded and folded in place

Update version of JQuery (jquery-1.1.2.pack.js)

Misc: Clean up "set" compat code

Misc: Create a branch for miscellaneous changes.

Improve the milestone creation and update operations.

- it's no longer possible to trigger an internal error when trying create a milestone with a name already in use (fix #3652)
- this error and others are instead presented as warnings, and the milestone editor is shown with the previous content. This is in order to avoid problems like #4100, but for milestones.

I also noticed that the data model classes `.exists` property is a bit confusing as this won't actually check if the object exists in the database. Improvements in this area are still needed (this is related to #4130).

WorkFlow: Based on the functionality added for querying status, enhance the
StatusFixer sample plugin to provide a dropdown list of status values, and
allow you to query for states that exist in the database but are not used by
any current workflow.

Less strict usage of the `Content-Disposition: attachment` header.
It's now the responsibility of each `IContentConverter` to send it if necessary.

WorkFlow: Fix comment in StatusFixer example plugin.

WorkFlow: Add a doc string.
