[chore] Common Header changes based on Brian's Feedback

	- All User’s can purchase in the Store so the cart should always be visible and not tied to having the Purchaser role. Currently if I uncheck the ‘Is Purchaser’ variable the cart is hidden. That restriction should be removed.

	- If the company isn’t loaded, the ‘Company Loaded’ variable is unchecked, I shouldn’t see the the notification icon or cart given I’m not registered with RVA.

	- Any User can navigate to a sub-company of their company so we can probably remove the ‘Can Change Company’ variable.

	- We should add a variable called ‘Is Administrator’ and only if this is checked will the User see the ‘Add Sub-Company’, ‘Company Settings’, and ‘Company Users’ in the company settings drop down (cog wheel).

	- The Help menu mouseover has rounded corners, the others are square. I think all should be square.

	- Under example settings I think we should have a variable for ‘Sub-Company Selected’ as this changes what is shown under the cog icon menu.

	- If a User is under their home company meaning they have not selected a sub-company, the Sub-Company Selected variable is unchecked under example settings, the drop down would look like the following with the name of the User’s company to the right on the home icon. In addition the option to ‘Switch To My Company’ would not be shown as the User is already under their home company.

	- If a User has selected a sub-company, the Sub-Company Selected variable is checked, the drop down would look like the following with a warning icon and the selected sub-company name to the right of that in red text with the following copy below that in red text. “This is a Sub-Company of your Company.” Above the ‘Select Sub-Company’ option there is now a ‘Switch To My Company’ option which resets the company selection back to the company that the User is associated with.

	- Additionally if a User has selected a sub-company, the Sub-Company Selected variable is checked, we should show a small banner below the header. The banner would be red with white text that reads “You’re in a Sub-Company of your Company. Current Company - name of the selected sub-company”
