Moved style variables
Moved style variables
Removed style variables
Style cleanup round 1

Still more to do, but cleaned up VMware style. Moved to CSS classes. Outlook probably needs a bit more effort, it's dodgy HTML rendering is a pain.
Multiple changes to styles

- vCheck.ps1 updated to new Get-HTMLList function for "List" display style. Replaces Get-HTMLDetail
- $TimeToRun variable now actually does something!
- Moved HeaderImg to vCheck and removed plugin - have some plans to work on image handling to give us the ability to embed images in reports.
