Typedal

Fix

* Improved JSON dumping with custom logic instead of pydals logic ([`ab9c3f0`](https://github.com/trialandsuccess/TypeDAL/commit/ab9c3f0be637942a472f4ffdba3effafc62460f5))

Fix

* Model classes can now have non-db properties and methods and pydal will not complain anymore. Config should all go via define, not as class properties anymore ([`49db4df`](https://github.com/trialandsuccess/TypeDAL/commit/49db4df2ff4c7ad2e9dad6cb78fab7ca7034a7d0))
