Force transaction functions to break if they modify controller state.  Do not make an assumption about the From gen_server data (it is more than a pid, so any gen_server:reply usage would have broken before, i.e., {pid(),Tag} == From, http://www.erlang.org/doc/man/gen_server.html#Module:handle_call-3).  Add integer timeouts to all the main boss_db functions. #79

Add all models within the running CB instance to DynamoDB
Add global/local config values for read/write capacity. 

Global values is stored in boss.config:
{db_read_capacity, X}, %% X is an integer
{db_write_capacity, Y}, %% Y is an integer


Local values is stored within the model as a function that returns a proplist:

dynamodb_settings() ->
    [
     {range_key, X}, %% X is an atom and should address one of the field within the current model
     {db_write_capacity, Y}, %% Y is an integer
     {db_read_capacity, Z} %% Z is an integer
    ].
