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!)
Load options.cfg with -user parameter

options.cfg outside of default locations is being ignored (bug 157)

Ensure we set up data, user and config folders after creating default
options and before loading options from file and command line.
fix: Not restored the button "NewBase" when you delete 8th base.
rare bug: If you have 8 bases and you delete one, the button "Build new base" will not restored.
put less-used cancel research button on the left
Unnecessary includes
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
fix: confirming dismantle facility

keyOk to confirm dismantling not keyCancel
well that didn't work out :(
Add keyOk and keyCancel to more screens

Adds escape and/or ok key bindings to perhaps better meet user
expectations in ufopaedia, geoscape and baseinfo screens.
Unnecessary includes
remove duplicated includes
