MDL-14493 First checkin of Feedback module into HEAD.
I made a number of small tidy-ups to the contrib version before adding this here: - fixed some language string names - renamed a capability from deletecompleteds to deletesubmissions (can we use "submissions" everywhere?) - got rid of language packs (moved english to correct location) - deleted 'pics' type (it needs to be rewritten to use user files in moodledata) - moved changelog into README.txt - moved captcha font out of subdir - bumped version to today Thanks very much to Andreas Grabs for all your work on this module so far, and congratulations! :-)
