Small feature addition to your plugin

Great plugin.  Much better than the bufexplorer i used for years, so I'm switching to yours.
However, I did not like how the bufstop split was forced at the bottom of the window.  When working with lots of splits in a window i found it hard using the bufstop at say a split on top of my window and then having to look down to select the buffer.  Additionally if I had vertical splits, the bufstop would move the text up and down,  which was distracting.
I prefer bufstop doing a :leftabove split which shows the buffers in the buffer you're going to change.
I added a quick option :BufstopSplit so one could configure the location of the Bufstop.
ex in my vimrc,  let g:BufstopSplit = "leftabove"

Thanks for your consideration, and thanks for this great plugin.
