Fix: Remove log window splitter size constraint, now the log window can be expanded as large as possible
Fix: Now preview window plugin will remember splitter location. If user manually change splitter size, all other documents with log window visible will have same splitter size.
Fix: If the log window is disabled because of no error found while building, splitter state will be saved such that other document with building errors will have log window correctly displayed.
Fix: Minor change to "Template file copy error" warning box.
