Allow grouping of tasks when running task --list --sort none

[JakeSummers]

Thanks for the awesome work on this project. Looks super great.

I am currently migrating from make. In our makefile we have a pretty ugly target that uses awk to parse the makefile and print help. It supports grouping targets into sections, which has been pretty useful.

Demo:

I was wondering if there was any desire to add this kind grouping functionality to task.

I agree, this is a great project. I currently use a help target as the .DEFAULT_GOAL in order to provide target groups and descriptions, and I think this would be a great addition to this project.

# the hack i currently use
.PHONY: help
help: ## Display help
	@awk 'BEGIN {FS = ":.*##"; printf "\nUsage:\n  make \033[36m<target>\033[0m\n"} /^[a-zA-Z_0-9-]+:.*?##/ { printf "  \033[36m%-15s\033[0m %s\n", $$1, $$2 } /^##@/ { printf "\n\033[1m%s\033[0m\n", substr($$0, 5) } ' $(MAKEFILE_LIST)

Hi @JakeSummers and @sonnysideup,

We currently sort tasks by the namespace. Isn't that enough? For example, if you have a bunch of tasks that start with docker: they will be shown togehter on task --list.

@andreynering I just noticed the feature last night when starting to work with the includes statement. I think I get it now, thank you.
