Refactored all settings pages, both user-settings and settings into separate (sub)components
Consolidated both setting pages into single settings modal. Old pages removed
Settings modal with ability to "peek" - minimize modal instead of hiding it, revealing page underneath so that you can check how UI looks like after changing the settings.
Tab-switcher now has top-tabs (default) and side-tabs variants.
side-tabs currently only used with settings-modal only and has some styles that only make sense for that component (mostly because mobile)
in mobile view content page will use ~ 99% of screen width + side tabs fixed-ish width, intended use is that you can scroll horizontally to show tabs or show content, and there's a tiny bit of tabs visible when scrolled to content so that you don't forget that there are tabs on the left side.
tab-switcher also has small upgrade to allow setting content pane 100% height, used for blocks/mutes tab.
tab-switcher's css was massively improved to properly handle tab-switcher-within-tabswitcher case, doesn't look very pretty but what can you do.
settings-modal (and hopefully everything it pulls) are loaded asynchronously now
updated vue to 2.6 to utilize Vue.observable to make async component resettable (if async component has failed it will stay failed forever without it)
fixed user-profile not using tab-switcher (?????)
What's NOT included:
All pages are left as-is, only split from original sources (user-settings or settings). Therefore some things looks a bit weird like "Submit" buttons on some pages originating from user-settings
Small exception - "mutes" and "blocks" tabs are merged into "mutes and blocks" with level-2 tab switcher to switch between mutes and blocks. Just made sense to do that.
