Bug Description

I have a CHM file with images, and some are not generated in the PDF. The reason is (again) that in windows paths and names are not case sensitive, but in linux they are. So basically the problem is there: a mismatch in upper/lower case somewhere in the CHM is enough. The CHM will display correctly in windows but you can't convert completely with chm2pdf.
The curious part is that in my case, the images not displayed where written correctly but they where in the same subdirectory with other images from other pages: and on one of the other pages the subdirectory was written lower case. So the page where images are missing in PDF is not necessarly the page where the mispelled upper/lowercase is, it can be on any other page. Probably what counts is how the path is spelled the first time it is encountered generating the CHM source file....
Anyone has some ideas how this could be solved automagically in chm2pdf?

This is the first time I try to generate a patch... hope this is correct!

- added (?i) modifier to make a case insensitive match for not breaking working links to images on windows in CHM files
- added " to the match criteria to avoid wrong match (eg this.gif matched also do_this.gif before)
