Bug: Fixed gift pokemon DV issues

[jojobear13]

In the master branch:

1. Gift pokemon going to the party were not getting DVs of at least 9,8,8,8 but if going to the box they were.
2. Gift pokemon going to the box would not have their current HP recalculated to match their new max HP.

In the lite branch: Gift pokemon going to the party got DVs as if wild while pokemon going to the box got straight random DVs.

This has all been fixed:

1. Any gift pokemon uses the wild DV function for random generation whether it goes to the party or the box.
2. In the master branch, any gift pokemon has a minimum of 9,8,8,8 DVs.
3. Gift pokemon sent to the box should have full HP now.
