Allow the port address to be reused. This permits running multiple SSDP

Allow forcing the inital window size for chrome.

(This allows working around an issue with kiosk mode where it fails to full
the fullscreen in some circumstances).
Replace tabs with spaces. Also remove redundant split.
Fix silly typo: --window-size, not --window_size
Merge pull request #44 from ywrt/master
