Support character alignment modification

[fmonniot]

Alignment is found in party.json, path /Descriptor/Alignment/m_History/<last>/Position. Example:

       "Position": {
            "x": -4.28543032E-08,
            "y": 1.0
        }

x is describing the lawful/chaotic axis and y the good/evil one. Needs to find out when the neutral switch happens but it looks like that follow the disc-shape layout of the game.

As of 82e86cd, we display the alignment.

Modification will require canvas interactivity (drag&drop on the pin), and this comes with iced-rs/iced#325. So we have to target iced master instead of 0.1.1 before we can tackle the remaining tasks of this issue.

iced released a new version (0.2). Once we have updated to it, we can tackle this issue
