PluginFormula rendering problem

I've noticed that when I enable PluginFormula and render some equations (specifically ones including exponentiation [^]), the image comes out OK, but often there will be some additional html garbage tagged on to the end of it... which doesn't look very nice. I was able to figure out that this is probably happening because the wiki renderer is interpreting the text inside of the IMG ALT field. A simple patch to include wiki "no process" tags in there seems to fix it up. The patch follows:

--- wikiplugin_formula.php

                }
                $file = $tmpf . ".png";
                $html = "<img src=\"temp/" .$file.
-                       "\" alt=\"" .$data. "\" ".
+                       "\" alt=\"" .$data. "\" ".
                        "align=\"middle\">";
        }
        return $html;

Filename uniqueness for wiki uploads

If I upload a file attachment to a wiki page, and then go to another wiki page and upload a file of the same name, then the first file will get replaced by the contents of the second without warning. So there is a uniqueness requirement to filenames for wiki uploads across the site. This is apparently only an issue if I use Admin->Wiki Attachments->Use a directory to store files.

Looks like file galleries (tiki-upload_file.php) avoids this problem by using uniqid(filename) to generate the md5 name to store on disk. Some small patches to tiki-index.php and tiki-admin_include_wikiatt.php seem to be all that's needed. (No such attachment on this page run through patch)
