Fixed needed rdoc version in gem spec
Changed prefix_for_link_defs to prefix_link_defs for path handler api
Small performance optimization
Item tracker now correctly handles UIDs that got invalid
Better caching in NodeFinder extension

If the reference node is not used by any filter in an option set,
it is not used as cache key either. This allows for more cache
hits for such option sets.
Fixed test for missing documentation
Added missing documentation for link_definitions
Fixed included tests in Rakefile
Fixed problem with item tracker missing_node when PathHandler#current_dest_node is not set
Added misc.dummy_index extension

This extension automatically generates dummy index.html files with a
http-equiv refresh to the correct destination for directories that
have a non-standard proxy_path set.
Allowing array values as default mandatory tag parameter
Fixed ItemTracker::MissingNode#item_description
Fixed webgen.cache config option to use strings instead of symbols

Again because of YAML problems with symbols in flow context
Fixed some configuration options to correctly work when used in YAML config file
Moved description field of config option to info.yaml

When defining a configuration option, the description is not allowed
anymore. It is expected that the description of a configuration
option is done under the 'options' key in the info.yaml file.
Implemented nicer interface to get at bundle information
Fixed API doc
