Update standard behavior of subcommand auto

New default behavior is to save the downloaded and processed files
to minimize unnecessary downloads and processing.

"import_data.py auto urls_file outdir --wipe": clean and restart the DB.
"import_data.py auto urls_file outdir": download and process new things
from urls_file.

Also, output directory must be provided manually as of this commit.

cleaned up playbook.yml
Merge branch 'import_data' of github.com:joelgoop/demokratikollen into import_data

Conflicts:
	demokratikollen/import_data.py
Fixed memory hungry cursor in populate_orm.py

Now it can import all "voteringar" without crashing.
Also made convenience bash-script for import.
Reimplement remove_col_in_insert

Now using a horrible regex, which probably is faster and hopefully
uses less memory than parsing.
Add chains for 'propositioner' docs
Increase memory in VM to 2048 MB

1024 MB was not enough to clean prop-2010-2013.sql. Next try was 2048 MB,
and it works well.
Add 'propositioner' to list of docs (urls.txt)
Merge branch 'import_data' into develop

*	Several improvements of import_data command line utility,
	not least making the `auto` subcommand more useful.

	Please see README.md for new instructions!

*	Added support for propositioner docs.

*	Changed how `remove_col_in_insert` works: Now uses a horrible
	regex instead, so it both takes and returns a string now.

*	Increased the memory requirements of the VM considerably, to 2048 MB.
	This was necessary to run a regex on some very large SQL queries (>120 MB).
Added mongo db support
