New XML-related functions & some minor fixes

- Fix for "man" function w/ PSCX's less.exe
- Add err and clerr aliases
- Add Format-Xml
- Add Out-CliXml
- Add In-CliXml
More NoteProperties on the $profile object
Use a PS job in Update-DlpGitProject for parallel updates

This actually works at the moment, but each job returns with a failure
and I'm not sure why.

Also:

- Fix some DLP client organizations
- Add .SerializeConstructorParameters() to DlpProject objects
Prompt changes
Remove deprecated code
Add work-in-progress for hex visualization using emoji
Prompt & clerr support for $LASTEXITCODE
