dynamic insertion for internal articleStore

[naggie]

Compare pubdates:

1. If newest, unshift
2. If oldest, push
3. If anywhere in between, look for a place and do an expensive operation to insert in in order

Of course, SQLite can do this with clever queries, not being expensive. So can Redis, prbably

also cache dump internally, invalidating when new article is added

This will allow for transparent g reader importing. Note that the articles are already checked for uniqueness!
