Limit cloud to min_count and/or max_keywords

You can limit using two values:

[loomingclouds]
min_count = 2
max_keywords = 10

The example will display only keywords with a count of 2+, up to a maximum of 10 keywords.

Counter.most_common(n) seems to return arbitrary values in the case that there are a number of equal values > n. Example:

>>> from collections import Counter
>>> c = Counter(dict([('a', 2), ('b', 2), ('c', 2), ('d', 1)]))
>>> c
Counter({'a': 2, 'c': 2, 'b': 2, 'd': 1})
>>> c.most_common(2)
[('a', 2), ('c', 2)]
>>> c.most_common(3)
[('a', 2), ('c', 2), ('b', 2)]

The min_count option will give more predicable results.
