#33 Bi-directional relationships are mapped with 2 unidirections
Channel and Item should be a single bi-directional
mapping. However from the current head of CVS, the
mapping files are defining 2 unidirectional relationships.
Currently Channel has a one-to-many uni relationship to
Item. And Item has a many-to-one uni relationship to
Channel.
It's important to fix this so that hibernate would not get
confused during deleting and update operations.

Correction: The one-to-many and many-to-one relationships
mappings from channel->item are correctly mapped as bi-
directional.
The one-to-one mapping in the channel object are correct and
are intentionally left as uni-directional.
The intended bi directional one-to-one mapping at the item
level are mapped as 2 uni-directional mappings.
Item->ItemGuid
Item->ItemSource
Item->ItemEnclosure
According to hibernate documentation, child objects like
ItemGuid should be using a one-to-one mapping instead.
