Allow Contributor Users to add Portfolio and Program icons to the main navigation menu

[#1]

Description -

Why is this feature important to you - Some users with a contributor license can more easily navigate by going directly to a specific Portfolio or Program to view relevant projects.

How would you like the feature to work - Contributor access levels can navigate to Portfolios and Programs from the main menu.

Current Behaviour - Contributor users can be given access to Portfolios and Programs and can navigate to them if the objects are pinned at the top of the page in their layout template.  The layout template allows an administrator to add these icons to the main menu but they are not visible when logged in as that user or by the user themselves.  This is a gap in access permissions that should be resolved.
