Business Model Enhancements Merged

The following enhancements to the business model feature will be very useful

• Ability to have more than one business model per product.  In most cases, you will have multiple models to account for different customers segments, channels, etc...
• Ability to save a custom business model and reuse it for other products rather than recreating the business model for each product
• Ability to make entries VIA a sticky note pad rather than just a bullet point.  Something like this https://next.canvanizer.com/demo/wA-82vhUOBc 
• Ability to change font color etc....
• Ability to add attachments that are not notes or to do's.  Just a general product document in the business model.

Due to these missing functionalities, we have to use a different tool in addition to Aha! and it's becoming cumbersome
