New research and technology page

* Added legacyworlds-server-beans-technologies Maven module, including
the player-level DAO and controller.

* Added session classes to carry technology information, modified web
client session façade accordingly

* Various changes to common UI elements (forms, lists, etc...) so the
start and end of some element can be drawn separately

* Added controller, templates and JavaScript for research page
