Help for common errors

At the topmost level of run, common errors need to be caught and help given to clarify what exactly is going on.

Validation Errors

Example:

  # Example::task
  class Example < Tap::Task
    config :a, 1, &c.integer
  end

% rap example --a blue
expected [Integer] but was: String

This cannot be caught easily elsewhere. It's not a config parser issue, it happens afterwards during task initialization. You want to be able to see the full backtrace on debug. As a result, the best place to catch/override is right at the top.
