Various classes are using member injection to inject extensible objects.
Really those object should come from an AdapterList that is injected in.
This patch switches the code to use setter injection that will later allow
spring to inject an AdapterList or something similar to allow
extensibility.
Also fixed existing bugs for the API:
* corrected action event to be VOLUME.UPDATE (was VOLUME.ATTACH)
* all parameters to update, should be optional - fixed that. If nothing is specified, the db object will remain with its original fields
- change the AccountService::isRootAdmin(short) to isRootAdmin(long accountId);
- Change all callers
- Change all places that check the account.getType() directly to call the AccountManagerImpl.
