configitems: register the full 'merge-tools' config and sub-options
We register the merge-tools config section (which has an arbitrary base config
value) and the possible sub-attribute. The sub-attribute has to be registered
first or at the same time otherwise the '.*' item would shadow them.
Merge tools could include "." in their name so we can't constrain any more
than just ".*".
