iOS UIKit v3 docs errata

Thought it would be nice to have an errata thread since I found one, and it might not be the last one to be found. (Hopefully we won’t have too many.)

SBUBaseMessageCell.message

SBUBaseMessageCell.message is implemented as an optional, but the reference says it’s a non-optional field.

To be honest I think it should be a late-init property (implicitly unwrapped optional) if anything, but it’s what it is.

Also, there are quite a few public properties missing for the said class, so maybe you guys have to regenerate the docs to match the latest release.
