[Charlotte.PM] Tidying HTML output / Temp Files

[diona kidd]

For temp files you could use File::Temp to generate unique temp file
names if you're concerned at all about overwriting or race conditions.
Couldn't you just hold it in memory though? I'm not familar with the
requirements of tidy.exe...does it need a file?
