Add ability to correct 0.5 second per day

Browse Source 
+ Added ability to fix timw skew of 1 second per two
   days
* Removed text of license as it shipped as file
* Fixed some grammar mistekes
* compflag now boolean
* Coding style fixes
* Tinker a bit values for brightness, again. Make display
   more dusk.
