Change mouse cursor on tabular selection zones

Browse Source 
This is done by implementing the clickable method. It is not possible yet to have the usual left and down arrows, because Qt does not implement them as far as I can see.

Factor the code that triggers row/column selection and fix the logic. Now it is possible to select also at the right of the tabular inset.
