README: fix typo
Added ask-passphrase flag to global options

* context.go - added global variable gAskPassphrase and added
  PromptForPassword() to get passphrase
* cmd/trousseau/before.go - updateCheckPassphrase() to update global
  variable
* cmd/trousseau/main.go - added Blooflag struct to give comments in help
Changed ask-passphrase logic

* gPassphrase in context.go
* helpers in context.go
* calling AskPassphrase from before.go sets gPassphrase
Support for AES-256

* put in the /crypto directory under a new package name: aesencryption
* this will use scrypt to generate keys from passphrases to be more
  secure than the initial method of iterative SHA256 hashing
* all messages will include the encrypted data, with a salt prepended
* added scrypt to GoDeps.json (revision number???)
* small test suite for the aesencryption package
* no integration tests yet
Fix #129: Make the passphrase and password asking more explicit
Update godeps
Export command without arguments prints to stdout [ref #125]

Minor cleanup - squash this commit into another

* deleted crypto/aes/aes.go - empty file
* clean up aes_test.go
