[IMP] web: improve traceback reporting

* Do not assault the user with a full traceback on bug, but indicates
an error occured and allow him to toggle the traceback
* Automatically scroll the traceback to the end (better for python
errors)
* Propose the user to report the traceback by using a new "Copy"
button which correctly copies the full error + traceback
