Option to show unrounded cursor cell coordinates

Is your feature request related to a problem? Please describe.
I use cell based coordinates in my game data or tiled object properties because they're usually more human friendly. And I use the mouse coordinate info on the bottom left to give me those coordinates. But since they're rounded, I usually have estimate how much into a cell the cursor is, if I want sub-cell coordinates. Since I'm doing isometric maps, there is the added difficulty of know the direction of the x & y axis (I'm still not used to it !).

Describe the solution you'd like
Have an option in the settings to round or not the cursor cell coordinates shown in the bottom left.

Start by locating the code that displays cursor cell coordinates in the bottom-left status area and the settings UI that controls display options. Add a setting for rounded versus unrounded coordinates, then verify the displayed values on both regular and isometric maps.
