Introducing Packages

Major Overhaul with Breaking Changes
split into packaged, default behavior moved into 'base' package
each package has a json package description file with criteria for
loading

Modified Setup-Profile to refer to 'base' package path for auto loading

moved Linux aliases and command to 'base.linux' package
created 'docker' package to address docker supported systems

modified Get-MyScripts, Edit-MyScripts and Reload-MyScripts accordingly.

Dropped -System and sys.*, package json conditions will take care of it.

Supplied command to create/edit package json files:
  - New-MyPackage
  - Add-PackageCondition
  - Set-MyPackage
