Reorganize tagging system

[Ernest314]

Maybe even for the entire ErythroGuild Github organization.

Make default labels more categorized - e.g.

• priority system (with color gradient):
  • Priority: P1
  • Priority: P2
  • ...
  • Priority: P5
• areas:
  • Area: Commands
  • Area: Web
  • Area: Build
  • Area: Docs
  • etc.
  • these might be project-specific, or have a large set that each repo can pick from
• invalid:
  • Invalid: Duplicate
  • Invalid: NotABug
  • Invalid: Obselete
  • Invalid: NeedsInfo
• types:
  • Type: Feature
  • Type: Refactor
  • Type: Bug

potentially need to go back and reclassify all past issues too...

Label names seem to be lower case by convention.
