The `effect` files are not translatable at the moment. The issue
lies in the fact that, even though the `effect` uses the Desktop
entry specification[0], it is not recongnized as such by `gettext`
because it uses the file extension to detect the supported files.

As a workaround for this problem, the files has been renamed to
include the `desktop` extension, which helps gettext detecting the
`effect` files. After the translation merge process they are renamed
to their right name without the `desktop` extension.
