patch notes [Dark Mode + Icons]

Hey all!

The changes from the deskGen beta branch have been pushed live to default, which means automatic (system synced) dark mode is now available in the default theme. If you would like to disable this, you can select the permanent lightmode option in the style selector at the bottom of the page.

Additionally, we have some fancy new icons from the ever-so-wonderful @noisivy to rep on the board index. Hope you dig it, and remember- it all happens on deskGen.
