DashClock: some TRDS adjustments

2 places Roman hardcoded the theme....add a TRDS configuration check
As well cleanup Android.mk and remove SDK version to get access to the
new Configuration API we use

As well small fix for sw600dp devices

And add a gray stroke around black color if TRDS is active so that it is not
black in black (calculate it on the base of the color does not work due that
black = 000000)
