LDEV-1051 and LDEV-1198: Fixed the break out of frames logic for parallels at the end of a design and inside an optional activity. Changing flag for waiting from boolean to a numeric flag.
LDEV-1227: Export failing when the content directory under lams-www/secure had an images directory but no files in the images directory. Wasn't detected the directory as empty (as there was an images directory) but the zip failed as there were no files in the zip file. Now the check for an empty directory checks for empty subdirectories as well.
