Create welcome screen form that allows for template downloading

[KenEucker]

Proposed solution:
Use all of the availableTasks requiredArgs to find ones that are common to all quasars, and ask them on the welcome prompt. Additionally, give a dropdown for the qType and provide download links to archives of template files based on qType chosen. Optionally output a json file of the welcomeArgs as well as a generated jobFile.

What's happening:
There is no welcome screen in the quasarWebform, and the welcomeScreen in the CLI only prompts for the qType.

What I expect to happen:
The quasarWebform and CLI should provide a welcomeScreen prompt that asks questions present in all availableTasks in addition to asking for the qType.

This work was started and I landed on the name "start" for this. Implemented as a quasar, this quasar generates a JSON file to be used in quasr to preempt the building of a quasar.

The UI flow for this should be:

1. What would you like to do? ( get started with a quasar, build a quasar, history, recently run quasar list )

• takes you to the next screen (start, build, or history)

2. Get started (choose a template by qType or qTarget )

• you will download a starter pack and the accompanying json file for the quasar template
• takes you to build screen

3. Build quasar ( upload assets, click build )

• does error checking on fields
• outputs valid quasar
• shows an intermediary dialogue after the build to preview the quasar (in mobile & desktop)
• takes you to history screen
