Don't visit po/ at all when translations are disabled
Made a unecessary global lua var local.
Made Lilly wait 2 seconds before healing Bronann when he is poor.

This is preventing her from healing Bronann in the middle of Banesore's attacks and looks better.
Made Harlequin's name unknown at first when encountering him.

This is a bit more logical.
Fixed map enemies behaviour again.

Simple enemy Map sprites kept on being blocked in a corner when losing sight of the hero until the hero showed up again,
and pathway enabled enemy were sometimes stuck idle after chasing the character.

Those two behaviours should now be fixed.
Added a proper battle AI for Banesore in the Layna village battle against him.
Added a proper way to trigger an event after a sprite dialogue.

This will permit to avoid tangling the map dialogue state and map event states
when adding an event at the end of a sprite dialogue.

The current dialogues made are using a hack I never got around fixing and I will do
so later if at all. At least, the next dialogues will be handled more sanely. ;)
Added a secondary quest in the Layna Village to test the latest API change.
cppcheck fix part 2/3.

Note that certain warnings are false positive due to the OS used or because
the code style chosen. I'll deal with the ++/-- change in another commit.
cppcheck fix part 3/3.

cppcheck output isn't clean but I won't deal with luabind related warnings
and false positives.

Closes #227
Added missing shoulders to two portraits.
Upgraded a bit the resolution changing code.
Initialized and update the overlay parallax members even when there is no ambient overlay.

This way, they can be used as info for other elements.
Added WIP Mountain bridge map.
Added and used the soldier on horse animation from Lilou.

It still needs an idle animation, and why not north, south animations later.
Started to adapt the editor to use the Qt Renderer.

For now, I only broke the main editor by removing videomanager bindings,
but fully adapted the tileset editor.

I'll use this simple example to create the editor view in another commit.
Started to remove broken code from the main editor view.
Made the editor able to load and display a map.

To achieve this, I had to remove the scrollarea QWidget and merge it
into the Grid class. This permitted to let the scrollarea handled by the QGraphicsView.

Note that the editor still can"t handle mouse events for now.
Removed the now unnecessary dependency files when compiling the editor.
