Resources information on planet list

* Added resource information records to the planet list's response.

* Added a database view and the corresponding row mapper and DAO method
which can be used as the data source for the planet list's resource
information. For now this view always returns 0 for both civilian and
military investments.

* Added new tab to display resource information on the planet list page.
The old version of the economy tab will be kept until the corresponding
data no longer exists.

* The following SQL scripts must be re-executed to upgrade a database:
