Version 2.1.0

Today's release includes some minor corrections and a few improvements:

- To help with data entry have added division and multiplication capability to the  transaction Amount field.
- Changed the appearance of the calendar window and added some options for its display,
- Future transactions that are entered manually show with a pink row background
- Scheduler has more editing capabilities and can now write individual transactions when required.
- Added German language (thanx to Chris)
- and others ...

I know, there are not a lot of improvements, but nowadays I am too busy in my office (= tired), I need much more relax than usually. I believe that things will improve.

Anyhow, thank to all who help me with developing program (not only by advices and bug reports, but by donations too).
