Extra parameters

We use a slightly different style for formatting PS code but still would like to use this formatter so here's a bunch of changes which gets it to the style we use. Summary:

• adding spaces after each comma (pretty common I think)
• treating all groups the same for consistency (so both @() and @{} for instance are formatted the same instead of the latter having spaces but not the former)
• custom function for spacing simply because we're so used to having e.g. $x | %{...} instead of $x | % {}
  All of these are optional so existing users shouldn't be affected, I think.

For reference, example of how we use this now:

$psBeautify = Get-Module PowerShell-Beautifier;
# Super-common aliases shouldn't be replaced
 @('?', '%', 'rm', 'cd') | %{$psBeautify.PrivateData.ValidCommandNames.Remove($_)}

# All of this is just so that Object gets turned into object, just like e.g. String is turned into string
$accel = [PowerShell].Assembly.GetType("System.Management.Automation.TypeAccelerators")
$accel::Add("object",[System.Object])
$builtinField = $accel.GetField("builtinTypeAccelerators", [System.Reflection.BindingFlags]"Static,NonPublic")
$builtinField.SetValue($builtinField, $accel::Get)

# Don't add space after ? and %
$customSpacing = {
  param($SourceTokens, $TokenIndex)
  if ($SourceTokens[$TokenIndex].Type -eq 'Command' -and (@('?', '%') -eq $SourceTokens[$TokenIndex].Content)) {
    return $false
  }
  $null
}

# Invoke beautifier with our options
