Display passwords in mono space font

[InnayTool]

Sometimes is hard to decide if a character in a password is for example an upper case i or an lower case L. So it would be cool if this could be displayed in a mono space font.

I see that the changes for this were reverted recently because they stopped working. However, the problem that this issue identifies is back again. Are there plans to do anything about it?

It looks to me like font-family: monospace could be added to the setStyleSheet call at mainwindow.cpp:1107.
