Removed redundant table CommitteeIdeas from database

This table was based on the many-to-many relationship between the tables
Committee and Ideas, which is not the case. Therefore this table has been
dropped and a foriegn key already exists in the table Idea that references
the Committee member that approved this idea.
Edited default value of integer columns

Integer columns if not initialized would have a value of nil,
which would not be usable.They have to have a default value.
Edited the IdeaCommittee relationship

This edits how the relationship was created. It was a HABTM relationship
and after editing it is a one-to-many relationship.
