use net-oce method hints on error

[tmpvar]

right now if you do display(cube(10).translate(10))

we should bubble that error up to the editor and show that error message at the correct location.

• [ ] https://github.com/solids/livecad/blob/master/frontend/js/client.js#L52-L54 should bail instead of bombing out. That can be achieved by resolving the future s(e) instead of throwing
• [ ] fix future wrapper to include the line # on the future (https://github.com/solids/livecad/blob/master/frontend/js/client.js#L24)
• [ ] utilize the line from the previous step to add an error into the editor - this should probably be done by adding an error method to methods (similar to https://github.com/solids/livecad/blob/master/frontend/js/main.js#L93)
• [ ] change net-oce argument hints to not include handle on op_*

Then instead of doing nothing on invalid args, it will show the user what they got wrong! Ideally at the exact character where it all went wrong
