Alternative IMP Background Selection

- two new options in ja2options.ini
 ALTERNATIVE IMP CREATION
- adds new additional backgrounds, exclusive to this option
- which IMP backgrounds will be available at selection is determined by previously made choices for skills, character traits and disablities
- if a tag in background is contradicting to content of skill/character/disability, it won't be shown at selection
- what's considered contradicting is based on what's been found in code for conntent of skill/character/disability
- i.e. HeatIntolerant adds a penalty for desert and tropical sectors, so don't show backgrounds that add bonus for those sectortypes instead
- a new tag <alt_impcreation, has been added to backgrounds for this as well
- if that tag is found, it will be considered as additional IMP background exclusive to the option

REDUCED IMP CREATION
- same as above, but this time only the new additional backgrounds will be avaialable at selection
- same rules for possible restrictions to be shown

ALTERNATIVE IMP CREATION is required for REDUCED IMP CREATION to work

For ja2options.ini, a new category, "Backgrounds" was created.
This will contain the two new options and the general option to enable backgrounds
