Add "generic" file/path models. Rewrite the stand-alone one.
Add AN UNRELATED to ORM function rrmdir (for recursively removing dirs).
Allow Import/Export to happen on directories, beside tar.gz files.
Allow COUNT function to work without a primary key.
Add "chainLoad" and "forceFilter" functions to ORM Collection.

forceFilter is for setting designated filter no matter what,
and chainLoad is the same as load (and takes same arguments),
but returns $this, instead of true or false. As the name suggests,
this is for chaining code style.
Adjust the way table name is fetched from ORM class.
Allow some usage of ORM with tables that lack primary keys.
Make many useless whitespace (and similar) changes.
More primary-key-less flexibility.
Widen the depth of assemble recursion.
Add a hack -- when left join loading, accuire both autofields.
Another useless whitespace adjustment.
