Allow for empty tab title

Is your feature request related to a problem? Please describe. N/A

Describe the solution you'd like Currently trying to use an empty character (such as a space) is ignored by Bonjourr. Well, not entirely ignored, I note that trying to use a space will change "New tab" to "New Tab".

Describe alternatives you've considered I have tried sooo many unicode empty characters to see if any would be supported, but it's not possible.
