``` [0] ~/sources/litclock$ python build.py --filename quotes/quotes_ru.csv --dry-run File with quotes: quotes/quotes_ru.csv Number of quotes with unique time: 441 (31%) ```

This fixes coloring in a ksh(1), Korn shell.

Executing 'cut' five times per line makes running script quite slow. Patch replaces 'cut' with builtin 'read' that splits string to a number of variables. This speeds up execution of litclock for three times for a worst case. Path to a shell in shebang has been updated: dash(1) on Debian is not compatible with POSIX shell, for example it doesn't support redirection. Default shell in /bin/sh is replaced with path to Bash. However, litclock script is compatible with Korn shell, that is actually POSIX compatible.
