Forgot to use Herth's new portrait in the battle against Banesore.
Fixed the dark soldiers speed when they're bringing Kalya to the riverbank.
Fixed a typo in a Kalya's basement dialogue.
Added all the missing custom minimaps seen in the forest dungeon.
Added a cap in the movement pixel computation.

This will avoid letting certain sprites movement go through obstacles
when the FPS are low, for instance.
Several fixes related to the minimaps.

- Made the minimap displayed within the rest of the GUI, after lightings.
- Made the minimap image loaded only if the minimap is requested to be shown.
- Prepared the engine to be able to reload a minimap on request.
Made Soldiers boss and add started adding rain into battles.
Added a beautiful yet discret ripples effect in battle when fighting under the rain.
Added a first version of Orlinn portrait, thanks to Anthony44! :)
New Orlinn's portrait by Anthony44 + small adaptations on my own.
