Fixed bug with JSON syntax error on reloading a page with sessionstorage

Added music player, and tested import of SVG, autoplay won't work in chrome because of policies, might use workaround

Add a method to directly set the page

Removed modulo operation for negative numbers, since it is not supported in JS

Only changes the font inside the ArtPAge. Can consider using Context to change the font on the top level entity

Add method in MainPage to change the currentPage state.
Passed the method down to LandingPage and ArtPage and created TS props declarations for it

The array should contain the different artworks
Indexing is based on the pageId

Intended to render everything that is visible no matter what page you are on. LandingPage or ArtPage

Add gitignore for .idea
