-- @brief Render user script HTML templates for all the available user script hooks
--        To locate an HTML template file, user script gui.input_builder variable is taken and
--        concatenated with ".template". For example, user script long_lived.lua has gui.input_builder == "long_lived"
--        will cause template "long_lived.template" to be located and then rendered.
-- @return Rendered templates in a table whose keys are hook names and whose values are rendered templates.
