v5.0.0.27: A few fixes and restores Windows 2000 support

This minor update fixes a crash of the Process Lasso GUI in Windows 2000 as well as a few other items.

• [.27]Fix.GUI: Fixed crash seen in Windows 2000. Note that process icons are disabled in W2K, at least for now, as the issue is in the new code to more efficiently resolve them using system APIs not available in W2K.
• [.27]Fix.Core: Fixed premature exit of default power scheme in certain cases where multiple default power scheme processes were running
• [.27]Fix.GUI: Fixed Russian activation dialog had User and Code captions reversed
• [.27]Fix.All: Fixed theoretical cause of settings being reset under rare circumstances
