domain_blocks 6.x-1.2

Bug fix release containing:
#704066: domain_site grant applied when unchecking all previous checked domains and checking new ones on block domain vis settings
#579044: Fails to detect new blocks?

Note: previous Domain Blocks version required explicitly setting block visibility settings. 6.x-1.2 version is now compatible with core behavior - an enabled block appears on all domains unless an exception is made (specific domain/domains are selected in block configuration settings).
