[windows] Improve cbcollect info formatting and usage

Along with our renewed focus on Windows, supportability needs to take a significant step forward IMO.

The current cbcollect_info does not seem to provide the same data that we find very useful in Linux.

A couple problems that come to mind initially, but I would expect that someone takes a broader look at improving it overall:
-The logs files seem to have binary characters which make them very hard to scroll through
-The couchbase.log file does not seem to have a directory listing the same way it does in Linux. I'm not sure if there are other areas missing.
