Options changed

Options now only accepts arrays
- then you can use array_key_exists|array_merge, so you can set default
options
Collection uses options, SqlHydrator supports array

The collections now extends IOptions
- so we can configure more easy your own collection

SqlHydrator
- hydrate: transform array values, to serialized values
- extract, checks for serialized data, and if is serialized it
unserializes it
SqlCollection now supports link tables

Well SqlCollection support link tables so you can easily manage many to
many relation ships
