Code improvments

- Code improvment with StyleCop / ReSharper defaults
- Some  variable names changed
- Better code formatting

Feel free to test all unit tests.. All except 12 are working but I could
have used wrong settings in app.config
Removed trailing whitespace (everywhere)

Visual Studio Regex:

Find:
[ \t]+(\r\n)

Replace:
$1
