Removed debug logging entry.
Excluded unused directives from index.html to avoid loading the files.
Renamed ".../directives/board-directive.js" to ".../directives/board.js".
Fixed problem where checkboxes didn’t show if they are checked or unchecked in Webkit.
Threads where the preview image takes longer than 30 seconds to load are displayed without preview image.
Development files can now be uploaded to App Engine (Workaround until asset compression is implemented).
Updated README.
