Visual Adjustment of "Appearance" Tab in Character Editor

[portfiend]

About the PR

this PR makes a lot of little visual and UX tweaks to the "appearance" tab in the character editor, including:

• separating it into collapsible sections
• moving "show/hide loadout/job equipment" and the "spawn priority" buttons out of the tab and to the top of the screen
• porting the "alternating color rows" control from General Character Editor Improvements Simple-Station/Einstein-Engines#2252, courtesy of DEATHB4DEFEAT
• making a lot of things multiple columns rather than just one very stretched out column
• adding a "scale" label to height/width sliders to show what size your character is being multiplied by
• merging the "background" tab into the appearance panel as a new section moved back
• rearranging controls in ways i think are more intuitive - putting names at the top of details, making "skin" and "eyes" color display side-by-side, etc

Why / Balance

the "appearance" tab has had a lot of different fields tacked onto it and has become, in my opinion, pretty cluttered and arranged unintuitively. there is a LOT of horizontal space that is not being used very well at all. certain controls being way too wide hurts visual comprehension. it is a very complex tab in a way that is kind of necessary for it to be that way so i wanted to make it a bit more digestible

Technical details

• i hit HumanoidProfileEditor.xaml with a hammer until it died and then i kept going until it was reduced into shreds
• removed the "background" tab and added the "dimension" label to HumanoidProfileEditor.xaml.cs
• ported that one control from EE, i can't get the commit for it directly so i just manually added attribution for it

after initial PRing the tabs have been rearranged a bit more, so Background is back in its own tab. here is what the Appearance tab looks like now:
