Make before_unfreeze and before_exec return self for chaining #16

Since we're changing the API anyway to return self, switch before_exec to unsafe like the standard library's equivalent did, and rename it to pre_exec accordingly. Rename the related error and field to match, to avoid confusion.

Merged. Thanks!
