Fix for #2215.

Fix milestone creation broken in [2387]. Closes #2241.

Simplify the path info matching of the milestone module, and use a different workaround to allow the use of slashes in milestone names.

Searching on multiple keywords from different table columns didn't work, closes #2129.

Follow-up to [2384]: don't show max-file-size error when the file hasn't actually exceeded the max file size. Fixes #1921.

Fix display of error message when a HTML preview for a file is not available. Closes #1921. Probably a regression introduced in [2276].

Allow checkbox custom ticket fields to be used in custom queries. Fixes #2166.
Also, removed hacks for Safari; those bugs appear to be fixed in Safari 1.3/2.0.

Cleanup for the TracBrowser navigation links:
* ''Revision Log'' link from the browser page will use the specified
revision, if there is one. This should fix #2239.
* ''View Latest Revision'' link from the revision log page will ''not''
use the specified ''start'' revision, but instead will go to the
youngest revision. That's more intuitive and anyway it's still possible
to browse the ''start'' revision by following the browse rev link found
in the first row.

Allow viewing the full file contents in the changeset view, by entering "all" in the context lines field (or in fact any string that is either not a number or a negative number). Closes #927.

Refactoring: moved milestone model class into `trac.ticket.model`, and the roadmap/milestone web interface into `trac.ticket.roadmap`.
