Built-in Tasks should use the native CLI args

[jwoertink]

A lot of the built-in tasks use ARGV and should just take advantage of our native CLI Args.

These are currently done:

• [x] - exec task
• [x] - watch task

These will require some thought on how to better do error handling:

• [ ] - security_key task
• [ ] - page
• [ ] - model
• [ ] - component
• [ ] - action
• [ ] - resource
