Server-side render pages

[davidsklar99]

For simple pages (ie lex pages where only map needs to be client side), most pages should be rendered server side.

This will allow us to create more complex tasks addressing #302 (like tests for certain class names, /map/.../column pages, etc.)

@davidsklar99 this is a relatively low-priority issue. We should first make sure that user-facing functionality is broadly up to spec.
