Update RouteTargetSyntax.md



this is not a valid route: 'GET /home': 'home/index'
i tested above in sails 0.10.2 (currently available on npm), i also poked around in ./sails/lib/router/bind.js and it doesnt appear to handle string route to view.
changed to : 'GET /home': {view: 'home/index'}

also added in a note for issue #194
