refactor(grunt:ripple): remove superfluous cordova prepare

[mmrko]

Ripple executes cordova prepare internally on browser refresh (see node_modules/ripple-emulator/lib/server/emulate/hosted.js). Thus, it's not necessary to call the Grunt prepare task to move files from www/ to the respective platform www directories.

@mmrko did you test this? You are correct that Ripple runs cordova prepare for you, but you must re-run ripple emulate if you want to be able to see changes. My findings are consistent with the note on this blog post - http://www.raymondcamden.com/2013/11/5/Ripple-is-Reborn

A caveat to the first note. When you edit your code, you do not need to run cordova prepare. Ripple does it for you. But you do need to rerun "ripple emulate" to refire the simulator. If you just reload the browser tab it won't show the latest changes. So you have a choice. You can either keep running "ripple emulate", or do "cordova prepare" in another Terminal tab so you can reload the same tab.

Thus, removing the prepare task like you did, editing a file, then refreshing the browser tab Ripple is running on does not work.

@mmrko I went ahead and removed the prepare statement from the initial task list, but for it to work as intended it needs to remain a watch task, as mentioned above f5d6d23

Oh, my bad! It indeed seems so that the internal cordova prepare is run only on full page reload, mere ⌘ + R doesn't seem to cut it.
