Checkpoint at block 193,000
Make 0-value outputs non-standard
Override progress bar on platforms with segmented progress bars

Windows & WindowsXP style have a problem with displaying the block progress.
Add a custom stylesheet as workaround, but only when one of those renderers is active,
otherwise leave the theme alone (issue #1071).
