Title: UPNP fixes and optimization

1) optimization: _xxxChilds: slice whole items array BEFORE converting to output objects
2) fix with special chars in items title.
Some players stops after receiving some special chars.
Don't know which exactly char is wrong, replace all special chars to '-'
3) auto refresh page - sending SSDP broadcast every second
