Token type markers

[supersaiyansubtlety]

Adds #139

based on #318

---

Adds markers for each token type:

• markers for each type are toggleable; only obfuscated and fallback are enabled by default
• markers can be limited to declarations; disabled by default
• markers have entry tooltips; enabled by default
• markers can be clicked to navigate to their corresponding entry
• up to two markers can be displayed per line; which markers are displayed is determined by priority:
  debug > obfuscated > fallback > proposed > deobfuscated
• higher priority markers are left-most
• markers have their token type's outline color (because it's brighter and more opaque than the main color)
