v0.2.2

Changes:

• Renamed Highlighter to Token
• Using egui is now a default feature, but it's optional. You can use Token, Syntax and ColorTheme beyond egui, e.g. to make colorful CLI outputs. Add egui_code_editor = { version = "0.2.2" , default-features = false } in your Cargo.toml.
• Fixed multiline comments behavior.
