LogWidget: Replace QTextEdit with QPlainTextEdit for better performance

Browse source 
QTextEdit is heavy, similar in functionality to WordPad,
while QPlainTextEdit is lightweight like Notepad.
Qt documentation recommends using QPlainTextEdit for log viewers,
and it also allows to set automatic cutoff of oldest messages beyond a fixed point,
which we now set to MAX_LOG_LINES (5000)
