Sample Project for DAL issue

superuser: admin/admin

When using DAL within django-nested-admin NestedTabularInline/NestedStackedInline, and a new row is added using "Add more Button" DAL fails to forward fields.

Replicating the issue:

• python manage.py runserver
• visit this
• The 1st inline text works properly, if you select anything in would not be shown in the list as Self() is being forwarded.
• If you add a new one using 'Add another Model Inline', it fails to forward Self().

According to nested admin integration it replaces this regex.

fix "dal-forward-conf-for-" to "dal-forward-conf-for_" to be matched in the regex.
