For Host only, set disconnect/disband to disband only

Change the functionality of the disconnect/diaband
button in the network fragment to serve as disband
at all times when you are host, and disconnect at
all times when you are guest.
Standardized whitespace in NetworkFragment

Accidentally autoformatted with tabs.  Changed
eclipse to use 4 spaces from now on instead.
