Platformio-atom-ide-terminal: Option to use Alt/Option key as meta key

[blockloop]

In OSX terminal, and iTerm2 there is the ability to use the alt/option key as the meta key.

From iTerm2 website:

Q: How do I make the option/alt key act like Meta or send escape codes?
A: Go to Preferences->Profiles tab. Select your profile on the left, and then open the Keyboard tab. At the bottom is a set of buttons that lets you select the behavior of the Option key. For most users, Esc+ will be the best choice.

Could we have this option for this package?

I would like to use ALT+B/ALT+F to move the cursor one word back/forward, respectively. Right now ESC, B and ESC, F works.

With alt I get the following characters

I am also used to the emacs commands and this would be an extremely useful option.

Is there any workaround for this? I'm looking at lib/view.coffee but I don't see anything obvious I can use in keymaps/platform-ide-terminal.cson.
