Modified protractor version

Protractor version "latest" was causing the following error when installing using ```clever init <package>```:

```
npm ERR! peerinvalid The package protractor does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer grunt-protractor-runner@0.1.11 wants protractor@>=0.10.0-0 <1.0.0

```
Changing the dependency version to one that matched *grunt-protractor-runner* needs - in this case, **~0.10.0** - seem to have fixed the problem.

Anyway, in most cases we shouldn't depend on a *latest* version, as this will probably cause incompatibility at some point in the future.
