Fixes /spaces/id/blueprint endpoint, when the id does not have a blueprint it returns the parent's blueprint.
FenixAPI - /canteen endpoint can receive lang and day queryparam
FenixAPI - About endpoint accepts language as query param
FenixEdu /about - Better locale handling.
FenixAPI /spaces/id/blueprint - Fixed yellow tag for rooms and buildings.
