Bookmark Menu: easier access to bookmarks

We've add a brand new field to our site menu options. You can now access all bookmarked activities and indicators from any DevResults page by clicking on the Bookmark dropdown menu. rn-bookmark-menu.png

You can also remove bookmarks more easily now be clicking on the star button next to the name of the activity or indicator you would like to remove. rn-bookmark-menu-unbookmark.png
