Fix parsing behavior of text-shadow property
Blur radius should reject negative values. There was already `Shadow` struct for properties like this. `filter: drop-shadow` also has the same syntax with that property. I thought sharing the same code would be better and used Shadow struct for parsing. Converted to SpecifiedTextShadow to get rid of unneccessary fields and to be able to convert its computed value. Maybe it would be better to avoid using `Shadow` or just using `Shadow` but sharing code and avoiding unneccessary fields seems better.

Bump base64 to 0.4.2
<!-- Please describe your changes on the following line: -->
we have just released a security patch for base64 (preventing integer overflow when sizing a buffer for encoded output). this bumps the version in the three Cargo.toml files that pull it in. there should be no observable difference in behavior, no non-malicious input should be able to trigger this state
