【Unity】AssetBundleBrowser: Bundle name 'XXXX' contains a period

概要

AssetBundleBrowser: Bundle name 'XXXX' contains a period.  
Internally Unity keeps 'bundleName' and 'variantName' separate, 
but externally treat them as 'bundleName.variantName'.  
If a bundleName contains a period, the build will (probably) succeed, 
but this tool cannot tell which portion is bundle and 
which portion is variant.
