Added pagnation to user playlists

[Peterwmoss]

Added some simple pagnation to at least scroll through your playlist. I don't know if this is the best way to implement it but it seems to work fine from my own testing. Please excuse if my Rust is "rusty", it's my first Rust project and I don't know if there is need for memory optimization for this change to not leak memory.

Thanks for looking into this.

Unfortunately, I've made a bit of a mess with regards to implementing pagination, which needs to be fixed.

But this looks fine for now.

Only thing to fix is the hardcoded offset

I spotted a problem with the navigation when paging so I added a check to see if the new table should be added to the navigation stack.
