Add home sections

[nielsvanvelzen]

I'm currently working on moving my personal library from Plex to Jellyfin and one of the things that annoyed me is that the sections I made in the web version weren't available in the TV app. So I implemented it!

I tried to make it look exactly the same as the web version but some things are still different:

• The library buttons are not implemented as I tried but couldn't find a nice way to implement it
• The "Latest Additions" section is split in the web version with one row for each media type, my implementation shows everything in a single row
• Editing the sections is not supported (I might add it another time in a separate pull request)

It took quite some time to get familiar with this part of the code because I haven't used Java in a few years (I use Kotlin primarily) and the structure of the app doesn't make a lot of sense to me because there is strong cohesion between most classes.

Thanks for the PR! The code is certainly a bit of a mess structurally. We’ve been trying to clean it up some as we go, but it’s a slow process. Just a heads up it may be a few days before this gets reviewed.

I rebased the branch as there were some conflicts in strings.xml.

I realized that the "latest additions" row is really annoying when all media types are showing. I also noticed that the feature of the web-home screen where you can select which (video-) libraries show in a single row doesn't work in my version.

This change should probably not be merged unless some more features are added, I'm not sure if I have time in the next few weeks to implement this as I expect it requires quite a lot of changes in the code to add this without using hacks to get it working.

@nielsvanvelzen I noticed a few minor issues in my testing also.

• User settings for sections need merged with the defaults (the preference only seems to contain a value if it does not match the default)
• Card heights are inconsistent in some rows
• Selecting logout does not seem to work

If you don't mind, I may continue your work here as this is a really nice feature! I should have some availability this week to work on it.

I don't mind! I assume you have more knowledge about the code base than me, I'm curious how you would add the missing features.
