Update translation template

[Víctor R. Ruiz]

There are untranslated strings, but marked for localization in the source code. The template needs an update.

[Víctor R. Ruiz (vrruiz)]

Byt the way, in src/youtube/scope/preview.cpp, this line is wrong:

{"label", sc::Variant(_(subsribedList.size() > 0 ? "Unsubscribe": "Subscribe"))

It must be:

{"label", sc::Variant(subsribedList.size() > 0 ? _("Unsubscribe"): _("Subscribe"))

The following strings are not translated yet and I can't find them in translations page:
https://translations.launchpad.net/unity-scope-youtube

Preconditions: language --> Spanish

Before login:

--> Tap on any video, here you'll see a button to login:

"Login to youtube" should be "Iniciar sesión en YouTube"

--------------
After login:

--> Tap over your profile picture:

"User channel" should be "Canal del usuario"
"View in browser" should be "Ver en el navegador"

-->Tap on any video, there should be 3 buttons:

>"Más..." button has the following bad translations:
- "Thumb up" should be "Like"
- "Thumb down" should be "Dislike"
- "Add to watch list" should be "Añadir a la lista de reproducción"
- "Add to favourites list" should be "Añadir a la lista de favoritos"
- "User channel" should be "Canal del usuario"

>"Subscribe" button should be "Suscribirse"
>"Post" button should be "Enviar"
