Enhancement: Add a save terminal/window/tab output

Hi George,

Loving iTerm but quick request. Not sure if I am just looking in the wrong place or it's called something different but it would be super handy to have an option to save the current scrollback/buffer or whatever it would be called to a file. Much like the OS X terminal Shell->Export Text As... option.

For now you can select all and do Edit > Copy with styles (hold down Option to turn Copy into Copy with styles).

Milestone changed to Feature Complete 3.2
