Title: Added option to avoid collapsing the last view expanded

It's something I am using in my current project, so you can expand all the Views without automatically collapsing the others just like the original ExpandableListView. Example:

((AbstractSlideExpandableListAdapter)list.getAdapter()).setCollapseLastExpanded(false);
