[ES] Suggestions and missing translations

[Yonseca]

Hi!

First of all, thanks for all your work and your effort 🙂 
I started playing multiplayer with a friend a couple days ago and I'd like to share some suggestions for the Spanish translations. These are from the Spain point of view, so they may not fit in other countries.

1. "Conductor": A train driver is known as "Maquinista". "Conductor" is used when driving a car or a bus, but not a train.
2. "Controlador de tráfico". This is today known as "Responsable de circulación". There are some more terms for this, as it has recently changed from "Jefe de estación", which may be more familiar for the elder. However officially today is not used anymore.

Then while playing in Dabrowa Górnicza, after clicking a point I found:

1. "Bloqueo de puntos en posición final". I think this is a literal translation from English. A point in English is what we know in Spanish as "aguja". Given that the "Stop" button actually blocks the point on it's current position to avoid it's movement, I'd suggest to translate the description as "Bloquear aguja".
2. "Anular el bloqueo de punto en posición final". It's the opposite, may be something like "Desbloquear aguja".

Same scenario, after clicking a level crossing, some of the buttons have missing translations:

• ZPO
• OZPO
• OPO
• APO
• APOP

Some pics of these translations can be found attached.
Thanks!
