fix for #358 from recent PRs (#390)

* camera offset for ui panels :

added maprenderer viewport to be aligned left or right

calling alignement on keyPress in game_controls

* check if already aligned

* fix bugs

-forgot to assign alignement
-defaultScreenRect instead of screenRect because of issue mentionned in original comment

* remove config.json and replace go.mod line

* update with new renderer and escape menu
