LDEV-1677: For all tools except q&a, mcq & vote, clicking Close on the authoring confirmation window will refresh the tool's monitoring window if the user is editing the activity from the tool's monitoring screen. Doesn't apply to define later or in authoring proper.
LDEV-1670 unordered lessons used to be appended in a non-guaranteed order (HashMap backed collection); switched to TreeMap, and prepend unordered lessons so that new lessons appear at the top of the list by default.
Removing all the repository stuff for the sample lessons so that CVS does not get confused with versions.Instead a single zip will be used for each release
