Replace files with sqlite

Using sqlite because sqlite has transactions, storing/loading from files
automatically, unloading data that is not accessed often.

Removed cosmetic data (node name, username). They can be added using
addData by the application that uses odhtdb instead.

Database callback functions can now be called with stored data using
database.loadNode function.

TODO: Add local user storage (with password) back, it has been temorary
disabled
