Rawtherapee broken download link

Hi,

Not sure this is the best forum for this info but the Downloads link on http://rawtherapee.com/blog/rawtherapee-5.1-released. Has a typo capital D and so goes to http://rawtherapee.com/Downloads where the correct link should be http://rawtherapee.com/downloads. Might be an obstacle for less technically minded users.

Thanks @nosle! Fixed.
