WIP implementation of the migration feature
See issue #66
Create a migration object helper
Create a `preserve` option to preserve form inputs across navigation
Use a class attribute on the form HTML tag to define the preserve option
fix "required" attribute
The migration across "Hot code push" is now working!
* Use the `created` callback of an `_autoForm` instance to register the form migration
* Use the `data` attribute of the component to retreive formId and `preserve` option
Rename "migration" into "form-preserve"
Remove the unfinished "preserve over template destruction" feature
Merge remote-tracking branch 'origin/ui' into migration
Merge pull request #67 from mquandalle/migration
