googleTrends addition

Let me know if there are some changes that should be done, I am testing this my self now and it at least has run two days in a row for me.
lines { 35-40 }. The suggestion is less repetitive.

```
subDesc = subDesc if len(subDesc) <= 10 else random.sample(subDesc, 10)
for item in subDesc:
    self.queries.add(item.strip().lower())
```
