Add icons to sidebar menu links

[Cleboost]

Updated the sidebar menu to display icons next to each link (Home, Tracks, Albums, Podcasts) by modifying the sidebar_link_widget to accept and render an optional icon.

Just a passing thought, the icons on the left of the sections are a nice touch. I'm not so sure about any of the changes to the search bar... I think having more space to use for your search query would be better than an icon.

I was also unsure about the search bar, but I still included it in the proposal; I can always revert it based on the feedback.

My feeling is that we should revert, it can always be another PR. I'd approve to add them since they are immediately more descriptive.

I'd also like @SO9010 thought on adding these icons as well.

Good idea, but I think it should be an option in settings to enable/disable it as I personally wouldn't want it as I I like just the test on the sidebar. But it could be an auto opt in feature.

If the PR is merged, I will submit a separate PR to introduce compact mode for the whole application. #663

I think the option can be compact mode

I'm a big fan of this idea! The compact mode could also have sub settings such as removing the info parts of say playlists and podcasts. Or changing the padding too? What do you think @jacksongoode

Hm yeah, I think we could sneak it under the show/hide covers.

As for other customization, since minimalism is the ethos of Psst (I feel). I wouldn't want to provide so much user facing customization given that it would also likely lead to breaking the interface. I think visual changes should be made sparingly and thoughtfully - though I'm not opposed to providing a stylesheet/config file that people could fiddle with all the constants at their own peril if they so desire.
