[aescrypt] PATCH: "AES Check" context menu command in shell extension DLL.

* Users can check whether they know the correct password for a file
without bulk decrypting it.
* Users can optionally verify the built-in integrity of the file without
writing out the plaintext.
* Progress bar dialog is now hidden when an exception takes place,
solving the problem of continued
progress bar animation underneath an error or informational dialog.
* Internally, the "encrypt/decrypt" bool which is passed around has been
replaced by a four-valued
action enum, including in the DLL API.
* The aescrypt command line executable which invokes the DLL supports a
few extra options to test
the new actions.
