IW disable auto new cell on running last cell

[janosh]

Add an IW setting to disable creating a new cell when executing the last cell.

Current behavior

# %%
print("hi")

When executing the above cell in IW, a new cell is added automatically.

# %%
print("hi")
# %%

Can't find a way to disable this.

Desired behavior

Input file remains unchanged.

Thanks for the suggestion. Seems like a good idea to me too. I use SHIFT+ENTER all the time and then it edits the file which I didn't want.
