Make Search/Filter/Sort on AllPage bookmarkable

[marianfoo]

What's new:

With this PR it is possible to bookmark and share the search in the All page.

What was changed:

• for the AllPage page a separate controller was created for a better overview. Many methods in MainView Controller are only relevant for this view
• the AllPage page is derived from the MainView controller
• the methods only for AllPage were removed from the MainView controller
• If the search/TypeFilter/Sorting is used, the 'HashChanger' automatically creates the bookmarkable hash
• When a URL is called, these parameters are read and the filter/sorting is applied
• FilterType and Sorting are validated

Testing:

The new function can be tested here https://marianfoo.github.io/artifact-of-the-month-bookmark/#/all

Please feel free to give feedback on code structure and application if I forgot any cases
