Updated the list of translatable attributes in translations containing HTML tags

We added the placeholder attribute to the list of translatable tags for the translation interface’s code highlighter.

It means the value of these attributes will be highlighted as translatable (in green) in the translation interface. We’re also working on major update to our word and character counter, and the value of these translatable tags will count in the word and character count. We’ll keep you updated in the changelog when update will be released.

The attributes we consider as translatable are currently: alt, summary, standby, abbr, content, title, label and placeholder.
