formio: Portal list or filter Forms by Resource type (e.g. Sales, Events)

[bobslee]

Currently all Forms available in the Portal (URL: /my/formio) are shown in a list.
Would be nice to have some filters in the Forms list.

Related issue: #141

For example filter shortcuts / profiles:

• All: all forms
• Resource Type: Event, Sales Order (filter field res_model_id)

Recommendation:
Checkout and study some other (core) Odoo modules which already provide this feature (sale ?)
