Consider placing RFC cache directory under XDG_CACHE_HOME?

[mlawren]

I've been trying to clean up my $HOME directory a little, where of course rfc adds it's cache directory. I was wondering if you would consider following the XDG_CACHE_HOME convention? That would possibly mean:

• Using $XDG_CACHE_HOME for the parent directory if defined; or else
• Using $HOME/.cache (and/or $HOME/Library/Caches?) for the parent directory
• Warning or automatically moving the RFCs cache from $HOME to the location

Good idea!

Right now we use $RFC_DIR with a default to $HOME/.RFCs. I changed this to default on $XDG_CACHE_HOME/RFCs if $XDG_CACHE_HOME is defined, or *HOME/.cache/RFCs if not.
I still need to add tests for that and add some code to migrate to the new location, and then I’ll release a new version.

Thanks very much!
