Leading zeros for time display.

Time is now shown with leading zeros.

7:9 is now 07:09
10:5 is now 10:05
Problem is that the windower api reference is incomplete and there is no description anywhere to be found how texts.new() works or the texts class in general. If i knew how it works i could maybe adjust this but since no one seems to care to maintain the dev wiki i just leave this as is for myself as i can not stand the time without leading zeros.
