b10-cfgmgr now prints the specific error on startup (and not a stack trace), which includes the full path to the bad file
moved ConfigManagerData.CONFIG_VERSION to config_data.BIND10_CONFIG_DATA_VERSION
bumped version to 2; including automatic 'update' (versions 1 and 2 are the same except for the format itself, in which case you can't even get to the actual value)
checks automatically use the 'current' value
