Disable window restoration altogether option

Comment from SRCTREE-1692 by Eugene:

"Is it possible to make this configurable or to disable window restoration altogether?
Most often I use SourceTree via the command-line helper, so when I run "stree <dir>", I already know what repository I want to work with, and I don't need extraneous windows (e.g. my previously opened repositories or bookmarks) to pop up.
Upd. That's an unfortunate reason that keeps me on SourceTree 1.5, because there this issue isn't yet fixed, and I can keep replacing "~/Library/Application Support/SourceTree/openWindowList" with an empty openWindowList file before actually running "stree", so that everything works as I'd like to."

Note, window restoration to be disabled, however running 'stree <path>' should open just that single repository window and nothing else.
