Review request for Dolphin.


Description
-------

I think this is one of the last things that should be fixed for 4.8.0. I had to add a new parameter 'index' to nextRowIndex() and previousRowIndex() to be able to reuse these methods for the PageUp/PageDown actions, which are performed by calling these methods repeatedly until the index with the target Y coordinate is reached.

The algorithm used to determine the new current index is a quick hack of mine, but I think it mostly does what Qt's itemviews do (at least in Icons View).


This addresses bug 288748.

Testing
-------

Works like PageUp/PageDown in Qt's itemviews with the following exceptions:

1. It does not work yet in Compact View (see TODO comment in the code).
2. In Details View, it does not take the header height into account.


Thanks,
