Overview

Added a new public method HttpRequest::url_for_map(), an alternative to HttpRequest::url_for().

Differences from HttpRequest::url_for():

• Accepts a std::HashMap of elements by parameter names instead of an iterator over elements.
• Delegates to ResourceDef::resource_path_from_map() instead of ResourceDef::resource_path_from_iter()

The common code between the two methods was refactored to avoid repetition.

Closes #628
