Autofill all modules when selecting first module in upgrade planner

[mr_abomination]

With the changes to the upgrade planner we can now specify what modules should be inserted into a machine when they are upgraded. However, you have to specify manually every single module in the row. Typically when I add modules to a machine they are all of them the same type, all speed/prod/efficiency/quality.

What I would like to happen is when the leftmost module slot is selected, all the other module slots are automatically filled with the same module and quality if they are empty. This would reduce the number of clicks when configuring upgrades and reduce the chance of error. This has been especially noticeable when upgrading machines with 4+ module slots and having any module quality other than normal; 5 clicks per module adds up.

If this is implemented, it may be a good idea to add a slight colouring around the first module slot to indicate what will happen.

Examples of this being done in various community tools/mods:
