Altered default Box Sync Folder Source to be ./ instead of ~/www/
Set default shared folder type to Default versus NFS unless source and target folders are empty.
Default document root on most web servers are /var/www and should be used as a typical starting point.
Set XDebug to not be enabled by default. Caused problems for some apps, so should require users to activate it.
Merge pull request #176 from adamculp/master

Typical defaults for some areas.
