Layout number inputs broken

[paulgirard]

for slow down and edge influence inputs (check others):

• input dose not accept float value (hit enter shows a invalid message)
• step should be 0.1

If I put a float number with a coma instead of a point (ex: 1,6 instead of 1.6), I have no error and I can't start the layout.
The start button is not disable, I can click on it, but nothing happened

BTW, to see the modifications, I had to click on "Reset application state" button

[sim51]

I also found an error on boolean input. I fixed it.
To reproduce it, just click on the Guess setting button two times. The strong gravity mode is then disabled ...

Due to the remove of the form validation, now we can send bad data (like the 1,6 in my previous comment).
I added a try/catch and notify of the error when you start a layout. So even if we don't prevent the layout to stat, the user will have a feedback that there is something wrong. And the graphology error are really good : "graphology-layout-forceatlas2/worker: the edgeWeightInfluence setting should be a number."
