better screenreader support (#309)

# Changes

* Overhauls much of template functionality to get some screenreader support in
  * Templates look for a `name.screenreader.template` file before `name.templatefile` if screenreader mode is enabled.
  * Failsover to normal templates if no screenreader template found
  * Attempts to strip out a lot of "drawing" characters and replace with spaces for everything that's sent
* `set screenreader` command (alias `screenreader`) enables/disables
* Created a couple screenreader templates for now - shop `list` table, and sunrise/sunset.
* Still some work to do, such as customizing behavior of prompts when screenreader mode is active.
