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 
the file.
