Include a Web shell for mobile devices

While having the ssh command to connect to the allowed targets as objects in the UI is nice, a Web shell for mobile devices like iPads would be great. Just connect to your target ssh using the warpgate UI. That way you could also secure the ssh access utilizing SSO, which currently only has a means for connecting to the Web UI, but not to any other target.
