[split] finagle-redis: switch from Int to Long for representing Redis integers Redis supports 64 bit signed integers (as stated in the docs, e.g. for the INCRBY command), and so Redis integers should be represented by Long rather than Int.

Here is an example of a Redis exchange that is currently not possible using the finagle-redis client:

redis 127.0.0.1:6379> SET foo 1
OK
redis 127.0.0.1:6379> INCRBY foo 1000000000000000000
(integer) 1000000000000000001
In order to support this I've switched from Int to Long in the following places:

INCRBY, DECRBY command arguments
Integer replies
Unfortunately this switch from Int to Long means a breaking change in the API, but it should be very easy for users to fix their client code.
