The uninvitedConnectionsPassword is written to ~/.kde/share/config/krfbrc in plaintext

Reproducible: Always

Steps to Reproduce:
1. In krfb, go to Settings -> Configure Desktop Sharing
2. Check the box "Allow uninvited connections"
3. Enter a password in the "Uninvited connections password" field, and click Apply
4. in a terminal, grep uninvited ~/.kde/share/config/krfbrc


Actual Results:  
Recover your password by reading it directly from the file (convenient!) ;-)

Expected Results:  
The password should be stored in an encrypted form, similar to the [Invitation_N] password= config option

~$ cat ./.kde/share/config/krfbrc
