Title: Reveal the current editing file in current NERDTree window instaead initiating a new one

When a tab already has a NERDTree window open, make `NERDTreeFind` use the existing NERDTree window instead of closing it and creating a new one. This would avoid unexpected results while a tab is using a mirrored NERDTree.
