Compiling CB with Erlang 17 RC2

[rambocoder]

Hi group,

Just wanted to give heads up on how to compile and run CB projects with Erlang 17 RC2.

"rebar boss c=compile" inside of projects will be blowing up due to this:

https://github.com/ChicagoBoss/boss_db/blob/master/src/boss_compiler.erl#L98

erlang:system_info(otp_release) return "17" instead of "R17", at least in 17 RC2.

A quick fix is to change it:

otp_version() ->

    OTPVersion       = erlang:system_info(otp_release),

    {Version, _Rest} = case string:to_integer(string:sub_string(OTPVersion, 1, 1)) of

    {First, _} when is_integer(First) -> string:to_integer(OTPVersion);

_ -> string:to_integer(string:sub_string(OTPVersion, 2, 3))

    end,

    Version.

PS. Several of the 41 dependencies will be not compiling in Erlang 17 due to their rebar.config files containg "error on warn" such as poolboy and riakc, or containing "R15|R16"
