Sync - staionUI complete rewrite in core.

This requires some action on our side, mainly:


* We need art for manufactureres : data/icons/manufacturer/
* We need art for shipclass : data/icons/shipclass/
* data/lang/ui-core/en.json needs to have every ship in lang file.

* All ships needs : 
ship_class=
manufacturer=

This works so ship_class defines what kind of ship it is, not the name, like Omni Explorer would then be something llike

name "Omni"
ship_class="Explorer"

* Possible police on our side not working anymore.
