CustomInfo for Systems

adding CustomInfo to the database along with a few tests for the model

migrating the db by adding a CustomInfo table and indexes

adding inflection directives so that custom_info is both plural and singular

adding the CustomInfo model with validations
	- the model allows multiple keys with the same
          name, but the combination of key and value
          must be unique on a per-informable basis

a few simple tests for the CustomInfo model

include custom info in 'system report' command
