Spreadsheet Example: Fix bug in update and minor improvementHEADdev

If the user drags a column from outside the visible area and drops it
into the visible area when the column contains a formula that depends
on a visible cell, updating that cell will not update the cell
containing the formula.

The reason is that the update method in the SpreadModel updates the
wrong rows and columns. The visible rows and columns need to be mapped
to the model's rows and columns.

The improvement is that the update uses a mutex instead of enabling or
disabling the connection in the view. However, the blockConnection()
function has been kept because some actions need to update a large
amount of data in the model, and then the view can be updated without
any extra view updates.

The pan and reset_reordering icons are updated. The new icons have
been designed by the designers.
