Version 0.3.2

Added SOCKS5 proxy support. See functions connectOverSOCKS5 and connectTlsOverSOCKS5.
Use safe-exceptions.

BREAKING CHANGE: Changed type of the following functions: getDefaultClientSettings, makeClientSettings, updateClientParams, clientParams, makeServerSettings, updateServerParams, serverParams.
BREAKING CHANGE: Only TLS 1.1 and TLS 1.2 are supported by default.
Server's choice of ciphers are always prefered over client's.
Server code will mandate strong cipher requirements, client code will be more permissive.

Re-export Socket, SockAddr, HostName and ServiceName from Network.Socket at Network.Simple.TCP.TLS.
Re-export Context from Network.TLS at Network.Simple.TCP.TLS.
Generalize the IO monad by using MonadIO and MonadCatch (from the exceptions library).
Added makeClientContext, makeServerContext and useTlsThenClose.
Use Socket as a TLS backend instead of Handle.
Drop dependency on monad-random-api in favour of monad-random.
