Gui: finally: Fix reload issue

...pls don't forget to copy the css to the website.

add on-click message

one more fix

ok, the previous issue is now fixed, too.

There is one very minor issue remaining:
If you click "reload"" the first node get no error-icon.
With the fist click to the workspace it reappears.
I'll do not fix that now.
Maybe one day.

Gui - add icon to all conflicting nodes

Gui - requirements

Update

+ check both for "shareable"

Step #1
Load and check for requirements.
Output - at the moment - on Javascript console.
Step #2: Make conflicts visible (with an Icon), and with a Text-Hint, eventually
