UX issues

Some issues I collected during my recent test of ewoksweb:

• On the landing/help page, the icon near Using Ewoks-UI is clickable but do not fire any action
• On the same page, it is misleading to keep Under construction help sections expandable. It can be frustrating for a user seeking help.
• On the workflow edition page, as a user, I get no feedback when executing a workflow.
• On the same page, clicking on the workflow title on the top-left has a non-trivial effect (it restores the workflow to a previous state?)
• On the modal to create a new workflow, clicking on Cancel button creates the new workflow instead of canceling its creation
