Added Debug Panel

-> added simple debug panel for manual adjusting sun and ambient colors
for each hour
-- panel can be opened by key "F4"
-- if panel is opened clients didnt update weather values
-- values were updated on every time panel were reopened, so there is
enough time to experiment with new values while panel is opened
-- with button "Print" sun and ambient colors were written to console
and chatbox

-> fixed all warnings on start/restart resource
