Online version of solid panes

Solid panes (previously solid app set) is a bunch of apps that can be used
to interact with linked data.

Above is an online version running on github.  While it may not have 100%
the full read / write functionality as running in your own browser or as a
shim (due to some CORS restrictions) it's hopefully a start on how to view
read write applications with both documents and data

* disclaimer the online version may be buggy in places due to not being
able to control the github headers etc. For best results run your own solid
POD and many of the errors will vanish.
