new default behavior and new options

[jeffhawke]

new default behavior: do not keep track of the ids of all the folders, only check a folder content against itself

new options: --all to automatically parse all folders, --global to restore the global check behavior for folders

Hi Jeff - I'm sorry for the delay in merging this - it looks good, though. My only concern is that the --global option changes the current default behaviour. I'm not sure if many people use this in scripts, cron jobs etc, but I wouldn't want to surprise them!

So I'd be tempted to leave the current behaviour and add a --local if you only want to check for duplicates in the same mailbox. What do you think?

Hi, thanks for answering. Yes, your solution works as well and it may be less disruptive of existing use cases.
Mostly, I went and changed the default behavior because I felt that only checking against every folder was the "expected" result, but then maybe it's just me.
