This is a quick fix for variant backgrounds and unarmored defense. I'm still working on the merging feature, which will be included in v1.1.0.

FIXES

• Variant backgrounds such as Gladiator, which is a variant of Entertainer, will now be converted correctly. Before this version, trying to import a character with a variant background would result in an error.
• Unarmored defense "armor" is now processed more correctly. More complex armor formulas than "10 + con" won't work though.
• Don't try to process the XFDF if the field is empty
