Allow for the abbr-tag to be removed while editing

Prepared a patch that removes abbr tag when empty title is applied, i.e. like in version 2.

According to HTML specification, the abbr tag may be used with or without the title attribute. In version 2 there were 2 form inputs, and it was possible to only remove the title attribute. Your patch doesn't seem to allow for abbr tag without title attribute.

I will look further into it as soon as possible. Feel free to provide another patch, and I will review it as soon as I can.

Hi @boromino,
I see. I have changed implementation by providing new Remove button and added command to remove abbr tag.
Now it's possible to add empty title and also possible to remove abbreviation altogether without need to remove text.
