Add ability for tasks to refuse composition.

As much as we really really want to discourage this use case, there may be times that a task should not be used from within another task - eg those that rely on the compiled project for introspection.
This issue is to track discussion on how to best support these use cases and minimise the potential pitfalls of doing so.
This is @jimsynz idea, not mine:
First, we add a requires_compile?: false
flag to Igniter.Mix.Task.Info
. Then, when calling Igniter.composing tasks, if we're composing a task with
requires_compile?: falseand there are any staged changes in the igniter, we show the user a diff & commit prompt w/ a message like
task foo.bar must write all changes and compile before proceeding(must will be in red). If they accept this, then we write everything and do a
Mix.Task.run("compile")` and continue on as normal.
