Merge pull request #38 from Grawl/master

update config for updated `node-sass` and support for `.sass` files
v0.9.8
v0.9.9
Added watch task to look for changes in the Gruntfile.js or grunt/ folder. If changes occur, reload the watch task
Added *.json files to watch in the project root.
Also created logic to handle grunt serve if config files are updated: watch and connect will not be called as they are already running.
So now user has the ability to change Gruntfile.js, grunt/**/*.js, and *.json files and see it auto reload with new settings.
Only caveat is that the watch config task will have to be restarted if changes are made
v0.9.10
add json file with local variables and add it to Jade task
