changedRomCount is not read correctly if the user has never touched the countdown toggle

[Tempystral]

EDIT: This was a mistake on my part. The variable was being updated but not showing in BizHawk.

The countdown setting is false by default, but this setting is not present in settings.xml until the user toggles it in the shuffler program. This means any setting below it in the list (e.g. changeCount) is read incorrectly into the application.

Setting defaults for all settings in setings.xml would fix this in the short term.
An xml parser module would fix this in the long term.
