Update TODO

- no charset supported on DOMParser.parseFromString().  Shouldn't be
  necessary, since the charset of the document should be specified within
  the document
Include jasmine via npm

- consistent with other node module usage
Cleanup import after Fcommand execution

- by revoking the import URL and removing the import once the Fcommand has
  succeeded/failed, its data is always available to the Fcommand itself.
  This supports Fcommands that take a delayed action after being invoked and
  the action requires data from the the import document.
Update TODO

- moving cleanup into page context is implemented
Remove unneeded code

- callResponseFunc is no longer used now that the Fcommand is run in page
  context
Remove test js

- test code in examples/load-jquery.html is currently hooked in
Update TODO

- add details on running bgcode
- add details on preventing simultaneous same-guid Fcommands from running
