Couchbase handle JArray support.

[Kriskit]

I had an issue where I couldn't store arrays/collections straight into couchbase using the BucketCacheHandle resulting in an InvalidCastException when BaseCache uses GetCasted to return the expected type.

I've currently had to work around this by wrapping up all my cached items in another object so that the deserialisation happens as part of a child property deserialisation automatically when ToObject is called on a JObject value type.

I noticed that there are a couple of checks to see what type the cache item value was and determined that JValue and JObject both inherit from JToken, as does JArray. Since JToken has the ToObject method it seemed prudent to only check if the cache item value is an instance of JToken.

This should allow all JToken derived values to be used.

@Kriskit thanks for the fix. Did you test it with a few different values, like simple string and a POCCO? I'm 50% sure I added those 2 checks explicitly instead of JToken for a reason. But I might be wrong ;)

@MichaCo I've tested it with a string, string[], int, int[], a single POCO and a collection of POCO's and seems to be working as expected.

I tested it using a console client in my codebase for testing our cache implementation which now wraps CacheManager.

Below is the output (note: I JSON stringify the POCO's in the output to see the values but they're definitely being deserialised from the cache properly).

Adding to cache:

Added value 'Hello World!' to cache using key 'String'.
Added value '["Test 1","Test 2","Test 3"]' to cache using key 'Strings'.
Added value '12345' to cache using key 'Int'.
Added value '[1,2,3,4,5,6,7]' to cache using key 'Ints'.
Added value '{"Name":"Test Item"}' to cache using key 'Item'.
Added value '[{"Name":"Test 1"},{"Name":"Test 2"},{"Name":"Test 3"}]' to cache using key 'Items'.

Retrieving:

Retrieved value 'Hello World!' from cache using key 'String'.
Retrieved value '["Test 1","Test 2","Test 3"]' from cache using key 'Strings'.
Retrieved value '12345' from cache using key 'Int'.
Retrieved value '[1,2,3,4,5,6,7]' from cache using key 'Ints'.
Retrieved value '{"Name":"Test Item"}' from cache using key 'Item'.
Retrieved value '[{"Name":"Test 1"},{"Name":"Test 2"},{"Name":"Test 3"}]' from cache using key 'Items'.

I hope this is satisfactory :)

One thing I'm a little confused about is, I tried to use the beta CacheManager NuGet feed to use the package that got generated from my pull request but it doesn't appear to have my change?? Did I miss something or is that not how it works? (don't actually use GitHub that much!) :)

ok sounds good /merged
The changes should be on myget in a few seconds I guess.

Thanks again! ;)
