Two categories named Internet in German translation

[kklavei]

In the German translation the category "Web" is translated to "Internet" beside the category "Internet" itself.
Please see https://github.com/linuxmint/webapp-manager/blob/master/po/webapp-manager-de.po#L65

This leads to two categories named "Internet" in the category list. Same behavior as described here for pt_BR #194

I suggest the category "Web" should be translated to "Web" or "Webanwendungen" or something else to avoid the duplicate "Internet" category entry.

On Polish translation there's the same issue (I think). The default webapps internet category is different from the one that appears in the menu on start.
