Simplify the cmdlet ("NameBuiltin") rule

This change simplifies the NameBuiltin pattern for cmdlets so that it highlights all cmdlets (i.e.: Invoke-Foobar) and not just ones built into PowerShell. It also places these as higher priority than language keywords, so you don't get odd formatting for Foreach-Object and similar.
