Progress bar widget enhancements

[kleinerwolf77]

While building a new dashboard using progress bar widgets, I had some few ideas:

• the pssibility to switch the progress bar widget from horizontal to vertical
• as I recognized, the widget does not only work with percentage values, it also works with plain numbers (only up to 100), it would be great if these could be used even when 100+, so a min/max value entry might be needed.
• as with the other text-containing widgets, some options for amendments of the text would be nice, too (size, alignment?)
