URL output

Have read the 'Spaces in filenames' section of your troubleshooting page but see no harm in adding a call to urlencode() in imagecache_create_url() for those who do not want to use the Transliteration module.

If the url works it may as well be encoded properly...

<img src='path/preset/example file (large).jpg'>
should be output as
<img src='path/preset/example+file+%28large%29.jpg'>
