Repeater initial size

[Vadim Gritsenko <va...@reverycodes.com>]

Hi all,

Found a bug in repeater with initial size and binding: after binding, 
repeater always has (amount of rows in model) + (initial size) rows. 
This is due to the fact that method removeRows in addition to removing 
all the rows actually adds initialSize rows to the repeater (as its 
javadoc states). And then, binding adds even more rows.

So, either binding should remove all those empty rows alltogether, or it 
should overwrite those empty rows with data, as per this patch:

If nobody screams... I'll apply it.
