Fix an issue with the reordering commands introduced in [2414] with newer versions of SQLite.

Add an `order` subcommand to the `priority`, `severity` and `ticket_type` commands in [wiki:TracAdmin trac-admin]. Closes #1909.

The `OneLinerFormatter` now collapse blocks into "[...]".

In order to make this effective, the line shortening is done within the formatter.
That change will be also useful in the future for implementing a truncating
that respects the Wiki syntax (see #2064).

Closes #2232.

Fix log warning issued when a chrome file was not found.

Fix some weird layout issues for the progress bar that happen sometimes when using IE. Fixes #1886.

During hotcopy, don't copy the database journal file (pysqlite backend). It's not necessary and on windows, it made the whole hotcopy process fail. Fixes #1123.

* Reenable the use of the `htdocs_location` for specifying the URL of the main static resources (source:trunk/trac/htdocs)..)
This should make it easier to deploy the Trac CGI on web servers that don't provide the configurability of Apache. Also,
it enables a group of Trac projects to use the same URL namespace for the resouces, thereby improving the cacheability of
those resources by the user agent.
* Remove the `diff/tab_width` option from the default config. This setting is deprecated in favor of `mimeview/tab_width`.

Escape ticket values in the query view for tickets that no longer match the original criteria. Closes #2243.

Fix layout bug in changeset view for empty log messages. Closes #1983.

Hack for getting the first item of the TracGuide TOC being highighted in IE/Win. Closes #1169.
