Remove unneeded background page

- it will be autogenerated
Update manifest

- add lots of new permissions.  Why so many?  Because this extension needs
  to be able to do anything.
- load only background scripts that are currently needed while refactoring
Start on help display
TODO notes
Use separate document for help

- since it's running in the background page context we can have it pull the
  help content after passing in an Fcommand guid
- remove the Blob stuff for the markup--no need to pass around markup
WIP: example fcommand to load jquery
