[mythtv] MythRemoteLineEdit and textChanged signal

[Leandro Dardini]

I am trying to adopt MythRemoteLineEdit instead of MythLineEdit in the
manual recording patch I submitted to the list few days ago.

MythRemoteLineEdit is derived by QTextEdit instead of MythLineEdit derived
by QLineEdit. This difference pop up when I try to catch the textChanged
signal. With MythLineEdit there is no problems, but with MythRemoteLineEdit
I get a "No such signal MythRemoteLineEdit::textChanged(...)"
I see in QT documentation that textChanged is a signal for both QTextEdit
and QLineEdit, so... why this kind of error?

Please in your reply consider my lameness in C++ and QT programming.
