Leatherman 0.12.x branch fixup

[Maggie Dreyer]

Hello all,

Breaking changes from the Leatherman 1.0.0 release were accidentally merged into the 0.12.x branch. In order to remedy this and remove the unwanted 0.99 tag from that branch, I am going to be resetting it to the 0.12.1 tag this morning. If you are using this branch, be aware you may see conflicts with your local copy.

Apologies for the mixup,

Maggie
