[Shotwell] 0.8.1 update: Problem with CR2 files from a Canon EOS 550D

[Bruce Smith]

Jim

Finally I found some time & built libraw 0.12.3 from source, then built 
Shotwell 0.8.1 from source & that dragged in the updated static libraw.

I confirm that this definitely fixes the magenta-stripe problem for my 
CR2, EOS 550D, RAW files.

Thank you for your advice.
