Missing translations and sidebar buttons

[Io-Qo]

In the current approval version plenty of language variables are not covered by the translations which leads to a mix of languages. So far I've noticed:

• "Waiting for your approval" as shown in the files app is not translatable (js/approval-init.js)
• the popup when you want to approve a file contains "This user requested your approval: [...]" which is not translated (js/approval-filesPlugin.js)

Also, the approve/reject buttons that were present in the sidebar are now gone which I find quite annoying as you now have to open a PDF, read it, then close it again, right click the file or use the new selector in the files app. Is this intended?

Otherwise I really like the new approved/rejected column in the files app.
