Merge branch 'mh'

Conflicts:
	scanner/indexdb.py
	scanner/scanner.py

database naming:
local db is dbfilename (/tmp/.auriq.db)
S3 db is dbname (.auriq.db)

I tried (untested) getting LocalScanner up to speed about
returning delim, compression, and records from open()
instead of waiting till get_records()

This may not fully work but it's close and Connor will let
me know what minor errors there might be.
