Announce - 0.8.6-rc3

[Alessandro Dentella]

I'm pleased to announce a new official release of sqlkit: 0.8.6-rc3.

Here are the main changes introduced.

sqlkit 0.8.6-rc3 -

* hooks: - hooks are now in a separated class that can be registered
globally under a nickname. If present 'default' hook
is used
- added after_flush and on_init

* layout: now layout can be registered globally in the same way
hooks can.

* validation: - added ValidationWarnings that allow to warn the
user but don't abort saving operation
- fix cases in which validation didn't allow to save
* fixes: after_flush signal

* fields: get_human value returs a formatted value (date/numbers)

Docs and examples have been updated accordingly
