Various updates

- Added Comment based help
- Some indenting fixes
- Get-PluginID now returns hashtable instead of array (removes $Title, $Author, and $Ver from plugin loop)
- Some capitalisations (because I'm weird and it bothers me :P )
- Simplified report actions (i.e. email, display to screen). Might behave slightly differently, but removed lots of duplicated lines of code.
- Possibly more I forgot about!
