[FIX] web: don't loose focus when editing cell in list

Have a list with readonly modifiers on at least one column.
Have the first record of the list be readonly as computed by the modifier
Create and edit a second record
Enter a value in the cell and hit TAB

Before this commit:
The focus on the targetted cell was lost and the rendering of the cell was in mode readonly
This was because the baseMode of the modifier dict was applied to one and only one node (== one column) and hence to *all* the records

After this commit:
The rendering and keyboard TAB navigation works as expected in the list editable
The baseMode concept has been sharpened and each cell now has one
