TracImgSvg no longer works due to a change in how attachments are stored.

[Nathaniel Madura]

See this ticket ​http://trac.edgewall.org/ticket/10313 for more details, but the attachments directory has moved to files/attachments and the attachment names are SHA-1'ed along with their page name.

Attached is a unified diff of a solution to the problem. note that wiki pages can have depth "some/page/to/wiki" which is why you can't assume the wiki page is in the 5th position of the array.

patch to get ImgSVG working on trac 1.0

Ahh crap, I did the patch backwards so the +'s and -'s need to be flipped.

like so...
