new uno command uno:Translate with deepl api

New Uno command added for translation
right now it is only using deepl translation api

There's a section in the options > language settings
for setting up the api url and auth key

uno:Translate is a menu button under Format tab
which will bring up Language Selection dialog for translation.

DeepL can accept html as the input for translation, this new
feature leverages that by exporting paragraphs/selections to
html and paste them back without losing the formatting (in theory)
This works good in general but we may lose formatting in very complex
styled sentences.

Translation works in two ways;
1) Whole document
when there is no selection, it assumes that we want to translate whole
document. Each paragraphs is sent one by one so that the output timeout
can be minimum for each paragraph.
2) Selection
