added a images_to_alt option to discard images and keep only their alt

[JocelynDelalande]

That's specially useful when you have big banner images in emails with an alt name.

Coverage decreased (-0.04%) when pulling c5d59f7 on oasiswork:jd-image_to_alt into 100ae75 on Alir3z4:master.

Is there any specific reason for having space around alt text [ ALT TEXT ] why it can't be stripped ?

[JocelynDelalande]

@Alir3z4 Well, it's more related to how the o() method handle its output. Honestly, changing that method behavior for my option seems overkill to me, what would you suggest ?

[Alir3z4]

@JocelynDelalande You're right, for now I don't think it would be a good idea to touch o since it might mess up all the unit-tests.

This change is fine then ;)

[Alir3z4]

@JocelynDelalande Is this gonna work if there's no alt on images? will the image be removed if there's no alt on the image ?

Yes, it just outputs nothing.

Awesome.
