tmux: play nice with iTerm2

Browse source 
That is, don't use reattach-to-user-namespace. iTerm2 provides an option to
allow applications in the terminal to access the clipboard, as well as deeper
shell integration utilities, which obviate the need for
reattach-to-user-namespace. What's more, iTerm2's tmux integration doesn't work
with it, nor when aggressive-resize is on.
