we may have fix for old file attachments

i think i found the problem with old file attachments, the yabb importer added 0x0a (newline char) to the end of filenames

this explains why the md5 hashes of the files were the same in vbulletin and yabb, but they weren't showing in browser. only the file names were imported wrong but i think i can fix this with a sql query

will be giving this a whirl shortly and then old file attachments that are images will appear in posts instead of as links
