New Dark Blue Theme and Updates to Existing Themes

[Lolabird]

Hi all!

I've made another theme called Ocean Dark. It has the same features as other themes I've made (discussed here), plus extra styles specific to TriliumNext for anyone using that version of Trilium.

For anyone using my other themes, I've also updated my existing themes, EverForest Ant Dark and Stellar Dark, to look and feel more cohesive with further plans in the works for improving the designs. They've also been updated to work with TriliumNext for people who need it.
