Multi-language Support for Buttons & Search field

[SylviaMoschner]

Hi,
it would be nice if I could set the text of the "previous", "next" & "view documentation" buttons in the config of my html-export. Also the "Search..." placeholder.

Hello,
Sure this is a good idea, I will add this variable to the templates.

Hi,

I made the change so that all the interface can be translated.

You can get this feature from the master branch directly.
