UI/UX tweaks and quality of life

[ZekeZDev]

This has turned into quite a large amount of tweaks I have removed and added some new functionality and tweaked some existing functionality. The major noticeable changes are:

• Redundant titles removed
  Before:
  
  After:
  
  This affects all pages including, settings, instance settings, instance creation, mod downloader.

• Also pictured above are search filters to be consistent now have placeholder text instead of filter: [search] it is now [Search and filter...]

• Rolypoly icon addded to icon selection
  

• Default instance icon is now the launcher logo

• Vanilla renamed to Custom, icon changed to launcher logo and tab background removed

• "Import from zip" renamed to "Import file"

• Profiles renamed to Accounts to keep consistency with other references

• install mods in version page removed

there should be some spacing there imo

[DioEgizio]

also it's not correctly alligned which is triggering me

tested it out too and I do agree, there needs to be a top (and right) margin

even with the built in fusion-dark it looks a bit too tightly packed for my taste

for comparison this is a system window in windows. matching the margin on all sides would be good i think. (should line up with bottom right buttons, etc.)

For me, it crashes almost every time the game is closed, but is fine otherwise. Win64 legacy portable.

still doesn't seem to have the margins at the top for me

Thats weird

[ZekeZDev]

this is what it looks like on windows

this closes #1078, so feel free to add "closes #1078" in the pr description

Need a solution for macos issues I also dont have a mac device for testing. If anyone would like to help contribute by testing mac for me that would be greatly appreciated.

wasn't there the idea to add the top margin as a empty extra widget with fixed height?
