Finx linkage when using C::B on windows.

The vsnprintf function was redefined with libintl and broke the build.
Added the Shroom enemy battle icon.
Added jumping animation to Kalya and Bronann useful for later.
Removed an obsolete monster stamina icon.
Added support to add an enemy post battle-start without explicitely giving its coordinates.
Basically finished the two first maps introducing the mountain climb maze.

There are still fluff to add here and there but its functional as expected.

I still have to figure out a bug happening when restarting the battle against
a dark soldier.
Removed an obsolete variable.
Added support for a missing Restart() function in the script supervisor.

Before, the reset function was badly abused for battles, making them
restart when the pause mode activated/deactivated.
Changed a debug value I left by mistake.
