A sound is played on new own private messages
On the latest version, a sound is played on new own private messages; in previous versions (for example lightIRC 1.3.2 Build 135) a sound is played only for the other user's new private messages.
Steps to reproduce:
1. Go to the Menu button, and select Options, then check "Play sound on new private messages or highlight"
2. Start a query with another user
3. Send a message to that user
Expected result: no sound should be played when the own message is displayed on the private chat window
Current result: a sound is played
