Currently we have one sqlite db which is responsible for mapping file urls <->
integer identifiers. We also install inotify watches on EVERY folder in your
home directory. When a file moves the db is updated.
This unique integer identifier (henceforth called file id), is used to map the
indexed data to the file.
When this "alternate" database will be used to store tags, ratings, etc
instead of xattr, at that time this file id will be used to uniquely identify
