Support "Descript.ion" files in Browse Source

[trac@…]

As the summary says...

Right now we hand edit a Wiki page describing each subdir and file.

The descript.ion metadata file is a quasi-standard by JP-Soft (4DOS) that Browser might be able to support.

Even better, there could be a setting like:

[browser]
description_top = README.first,.title
description_bottom = .trac,descript.ion,README.trac,README.html,README.txt,README

which could be used to pick one entry among the folder entries which will be previewed in the browser folder list, on top or after the entries list itself.

The preview would be done the standard way, so it would be possible to use wiki formatting either by setting the svn:mime-type property on a README file (if using svn), or by using mime-type associations in mime_map (e.g. text/x-trac-wiki:trac).

Using an ordered list is useful so that you can eventually add a special file (.trac as in the above) to prevent some existing README file to be shown, when this is not desirable.
