Honor Menu Capitalization (and Custom Name)

The Survey module creates a menu item called "survey" under "create new" (in v1.18 it's line 48). This should be "Survey" to be inline with the Drupal 5 capitalization conventions, and though it can be corrected using /admin/build/menu it's an unnecessary extra step for folks installing the module.

Even better would be to make sure the menu item is kept in line with whatever's being stored in the {node_type} table under 'name', as that can be changed by the form at /admin/content/types/survey.
