Add !help support for Examples, Full help content

[RamblingCookieMonster]

Add !help support for Examples, Full help content, and adds single character aliases for these to simplify use in Slack, without completion (e=Examples, f=Full, d=Detailed)

Hit me up if you'd prefer another route, figured this is reasonably benign - existing behavior remains, just adds params for others

Description

Adds common Get-Help switches to !Help - Full, and Examples. Examples in particular are quite helpful, Full may come in handy if you want to describe or see further information in parameters and other help content Detailed leaves out.
