Just thought you'd like to have this. I hex edited chromatic to use the new URL's for nightlies and all is working fine now. You can download it at http://dl.--dropbox.com--/u/970025/Chromatic.zip

NOTE from TheM: remove the dashes from the domain if you really want to download it. I've not tested it and I'll wait for the official release. So use it at your own risk.

Added version check. Omitting download if unnecessary.

Note to myself: do not add more features in a simple bash script, even more Perl is required
