Call --list from within taskfile.

[rangerjo]

As a default task I wish to call task --list. This will display the builtin summary of all available tasks. Unfortuantly, some distros (eg. Arch) package task as go-task, so the above default task would fail.

It would be nice to either

1. have a global Variable similar to CLI_ARGS avalible that holds argv[0], or in other words the command issued to run task, or
2. call task --list from within the Taskfile just like calling any other task without exiting task.

Hi @rangerjo,

In the next version, a new special variable will be available (#1624)
TASK_EXE will hold argv[0]
