Q has no method 'getUnhandledReasons'

[tarmolov]

When I specified debug option in the config file, I'll got the following error:

TypeError: Object function Q(value) {
   // If the object is already a Promise, return it directly.  This enables
   // the resolve function to both be used to created references from objects,
   // but to tolerably coerce non-promises to promises.
   if (Q_isPromise(value)) {
       return value;
   } else if (isThenable(value)) {
       if (!thenables.has(value)) {
           thenables.set(value, new Promise(new Thenable(value)));
       }
       return thenables.get(value);
   } else {
       return new Promise(new Fulfilled(value));
   }
} has no method 'getUnhandledReasons'

hermione uses q library v2 which doesn't have getUnhandledReasons method anymore.
It seems that q-debug-mode is useless now and can be pruned.

Seems q is not being used anywhere except qDebugMode in lib/hermione.js. Need to remove in order to fix lint issues.
