Empire mining settings

* Modified mining settings stored procedures to use text identifiers
instead of numeric identifiers

* Added DAO for mining settings and controller for resource operations

* Added UpdateEmpireMiningSettingsCommand and associated command
delegate. The command always returns NullResponse.

* Overview page templates split into multiple files for clarity, added
priority update form to the empire economy view and associated web
server handler
