V1.0.18 released

Fixes :
- In texts ammunition was not taken into account in some places. This was fixed.
- The first time you walked on an unavailable shop (from which you were thrown out) after reloading a save game it was impossible to walk forward (before opening a menu and getting back). This was fixed.
- Thrown back status changes could be displayed more than once in the combat log. This was fixed.
- When an Insensitive character would lose the status instead of taking damage the displayed damage was not 0, now it is.

Changes :
- A save menu where you can directly select existing files replaced the simple save command.
- A feedback text was added to state when a character resists an attack which cannot make any damage but only inflict a status change. 
- There was no particular text when failing the mental resistance test with a Braineater. It was added.
