Feature Request: Ability to change default clicking behaviour on map tools

[OrangeDecay]

Problem to be solved

I was using byond dmm editor for about 10 years and so i am adamantly used to clicking without hotkeys to replace things and ctrl+click adding things, however default behaviour of tools in Strongdmm are different, which in itself is fair, someone is used to using that as well.

Sugest a solution

So i think a solution to this is to add the ability to choose the default behaviour of mouse click, as well as ability to choose what button you have to hold down to achieve replace/add/fill functionality. Same goes for Pick, Delete and Replace.
