add TryParse() methods to Redis.Value for common conversion; exposing publicly functions already available internally

expose Prepend and Append methods on RedisKey, so we can avoid some string concats in common cases

add TryParse() methods to Redis.Value for common conversion; exposing publicly functions already available internally

Fixed typo

Revisit prefixed keys to avoid allocations; update MS redis-64 from nuget; update tests; change namespace of keyspace isolation - that was an error

Fixed race condition in PhysicalConnection creation

Make locking *mostly* work with twemproxy (and more generally: without multi/exec if they aren't available)

Make sure the initial cursor/pageOffset are correct (for both enumerable and enumerator) even if not iterated

HLL unit tests

Issue #99: Added HyperLogLogLength that takes array of HLL keys

Fixup the `[InternalsVisibleTo]` (glitched on strong-name version, but not needed);  include Moq dlls - this is purely to make my build-server happy

Key space isolation tests

Minor change to WrapperBase

Merge new stuff
