This is for when using ImageMagick to create thumbnail of only the first page.

Modified source to look like /path/filename.pdf[0] instead of /path/filename.pdf.

Doesn't seem to have negative impact on other file formats.

NB: Testing is needed, and this probably only works when using ImageMagick.
Added a timeout setting to use with urllib2 when retrieving an image with a URL. Without the timeout setting, urllib2 will wait indefinitely for a response.
replaced thumbnail.exists() assuming that if the thumbnail is not cached it does not exist
if THUMBNAIL_DUMMY is true all thumbnails always replaced by dummy.
