Add text parsing to `Text` component

[benrucker]

Rules:

• Single curly braces mean text styling:
  • {text | italics} should render: text
  • {text | bold} should render: text
  • {:cheeto:} should render the cheeto emoji
• Double curly braces mean a value is needed:
  • {{userMessagesThisYear | int}} messages should render to something like: 5,123 messages
  • ... in {{userFavoriteChannel | channel}} should render to something like: ... in #spam (with cool styling)
