Allow loading of .bib file from htdocs

[pauld.mccarthy@…]

Being able to store and load a .bib file as a static resource from the htdocs/ directory is useful for me. I have a single .bib file, containing all the references for my work, which is under independent version control. With the patch below, I can simply create a symlink from htdocs to my .bib file, so I don't need to maintain a separate .bib file.

Using the patch as-is, to add a .bib file stored in $TRAC_ENV/htdocs/library.bib, you would type [[BibAdd(static:library.bib)]].

Since r11553, as part of a full rewrite its now possible to load bibtex files from everywhere in the web.

Example:

[[BibAdd(http://www.example.site.com/bibtex.bib)

Its not exactly what you wanted, because I don't like the idea of hardcoding something for the symlink, but you can have the same effect by using the 'http' prefix and securing your file via your webserver.
