Kdenlive default layout names translation

[Yuri Chornoivan]

Hi,

After some code rewriting for 20.08 release in July, Kdenlive lost its ability 
to have translatable default layout names (see the screenshot attached).

I'm trying to renew this feature with a trivial patch (attached). It does work 
somehow (extracts, translates the button labels and actions, etc.), but breaks 
the button change logic. Can the patch be enhanced by some of the more 
skillful Kdenlive main developers to make the default layout names 
translatable?

Thanks in advance for your help.

Best regards,
Yuri
