View source in 1.2.0 docs links to 1.2.0-rc.3

The view source button in the 1.2.0 docs links to the 1.2.0-rc.3 tag. Not a huge deal but sometimes points you to the wrong line in the source.

I suspect this will be fixed by #4909

Assigned to @petebacondarwin so he can check...

This issue is NOT fixed by #4909, which I've just finished reviewing and merging.

@petebacondarwin if you're not working on a fix for this issue, or planning to work on one soon, go ahead and unassign it so someone else can work on it.

I hope I fixed this in the master, so 1.2.1 docs should be fine.
