Started to add rudimentary (and probably the most important) stage of healing your pets and companions; trying to stop bleeding of their wounds.
More companion/pet healing methods may follow in the future, but we'll start with the most crucial one.
The mechanics of applying physical skill to your companions are the same as applying them to yourself. Herbs can be used in the process, the success or failure messages are the familiar ones, and so on.
How an attempt to heal your companion is started is to face them upon using physician skill. If treatable wounds are found (ie. bleeding wounds) you'll be asked whether you wish to try applying the physician skills to this companion or pet. The wound to treat is then auto selected based on its severity.
