graph queries

[trashhalo]

• add a way to bulk change the appearance of pages in graph by using simple queries.
• persist them into a page
  • each block a query
  • block properties control node changes
• options to change
  • icon
  • color
  • visible
• consider a in graph interface for adding new queries, think obsidian

@mrparalon do you think your pr closes this issue?

I think no, at least visibility by query will be really useful. And icons will be easy to implement
