docid_to_date discards useful file path information

[JustinAzoff]

a filename like

turn /data/nfsen/profiles/live/podium/nfcapd.2009030110

gets turned into

"2009-03-01 10:00"

but the path contained potentially useful information like profile='live' and source='podium'

I need to replace doc_id_to_date with something that keeps this information

50% complete. Backend support was added in 6d986a1ab55f2ed0d9d2ee03e61772942a71a896

'pathregex' is the new configuration option that can either be a real regex or a simple string like profiles/:profile/:source/

Remaining now is support in the CLI and CGI for controlling what fields are output
