#3 Save system 2 and workshop implementation

Hi ! 

this prototype is starting to flesh itself out, however I decided that from now on I will only update the Downloadable .exe at each iteration, and the Web one only from time to time. 

Updates:

-character and their jobs are saved

-you can create recipes from the workshops

-tile selection system updated

-you can rotate the camera with A and E and X and C keys.

-you can trigger the Isometric view with I (still some problems to solve with that)
