This set of commits implements the bootstrap commands,
following from the description in #117

Removed config.Filename and replace it with config.GetConfigFilePath that
takes a configuration directory as argument instead. Makes code simpler.
ipfs.getConfigDir now also return the default configuration dir instead of
an empty string in some cases.

let's keep this a turn-on for testing sort of thing.
(want the outputs of commands like `ipfs add` to be
usable as inputs to other programs/scripts).

maybe we should consider adding a --debug (not -d),
once we figure out adding flags that apply globally :)
