lok - sc: invalidation of cached row/col positions on several cases

Cached row positions are invalidated when one of the following event
occurs:

- one or more rows are inserted
- one or more rows are deleted
- one or more hidden rows are made visible
- one or more visible rows are made hidden
- one row is resized
- optimal row height is changed
- the value of the PPTY parameter is updated
- a undo/redo involving any of the above actions

The same occurs for cached column positions.

The solution takes care of row/column operations performed in another
view and of the current tab each view is displaying
