allows the statusline to be customised for the nerd tree window

*remove the change log prior to v3.0.0
*remove the todo section
*change "about the author" to "about" and put the github/vim.org project
urls in it

remove "top" and "bottom" as valid settings for NERDTreeWinPos

Do an unlet <old key> when over riding a method on a prototype object.
Some older versions of vim spaz out otherwise.

Note: i was using these unlets up until a few versions ago when the were
refactored out
