Initial js validation code added
Error displaying improved
validation improvements
inline positioning of error boxes
use underscores in class names
Use FormData for data collection and submiting.

Disable validation for IE<10
Use mass_assigment_actions method for retrieving action names
More convient solution for globalize3 and validation fields targeting
Initial nested attributes field_id support
nested fields client-side update
adapted translations controller to new nested fields code
fieldless errors and some more validation changes
removed debug code
Use name attribute for validation field matching

This is more reasonable solution as there can be radio buttons with
different ids but same name. And rails validation anyway validate model
attribute (name) not id
Do not move removed items
reindex only new items in nested fields
match alternative attribute syntax with underscores during reindex
Fix typo and use edit as fallback for create/update redirect if show not
available
Fix path helper call
