Updater: minor improvements to o4logtool.html

1. Fix Windows command-line parsing (command lines end in \n, not ' ').
   This allows the tool to consistently color the internal/non-internal
   services on Windows instead of making them both red.
2. Fix crash handler detection. This change was already present in the
   internal version but I forgot to check it in.
3. Adjust the base color of --install to make it more distinct from
   --wake; I couldn't tell the difference while scrolling through.
