add cancel button to researchInfo popup

- cancels out of adding a new project
- stops a project that is in progress and refunds any allocated scientists
Added polish translation (thx Krzysztof!)
put less-used cancel research button on the left
restore items when research project is cancelled
ensure required research items are removed/added
/don't/ remove/restore items; just aliens
respect containment limits if cancelling research
don't transfer aliens to bases with no containment
