More noticeable features in the inventory page

[OlaBekkevold]

The user experience in the inventory page can be improved by adding text that point the user towards thing to do and make them more directly accsessible instead of hidden behind menus.

• Add seperate buttons for activiting loan and edit menu
• Mark the form for adding new equipment

This issue is mostly completed but there has been feedback on the feature saying that it is still confusing. And an improvement would be to label the loan and edit buttons with what they do and potentially also adding some form of tutorial in the beginning.
