runtime: implement an extensible line editor

the line editor supports custom keybinds and data storage, allowing for
a wide range of functionality to be implemented via plugins.

included plugins include:
* core: basic input and cursor movement.
* history: input history storage and retrieval (unfinished)
* highlight: support for colour-highlighting the line buffer (unfinished)
* syntax: parses the line buffer and uses `highlight` to apply syntax highlighting (unfinished).
* shell-integration:
  - allows a `prompt` function to be defined, which will be called to get the text to
    be used for the prompt
  - exposes key properties of the line editor to the shell environment, allowing line editor
    functionality to be extended via shell scripts.
