Update fabric to 0.9.3

Pkgsrc changes:
- add depends to py-crypto

Upstream changes:

0.9.3
=====

Feature additions

* #255: Added stderr and succeeded attributes to local.
* #254: Backported the .stderr and .succeeded attributes on run/sudo return
values, from the Git master/pre-1.0 branch. Please see those functions? API
docs for details.

Bugfixes

* #228: We discovered that the pip + PyCrypto installation problem was limited
to Python 2.5 only, and have updated our setup.py accordingly.
* #230: Arbitrary or remainder commands (fab <opts> -- <run command here>) will
no longer blow up when invoked with no fabfile present. Thanks to IRC user
orkaa for the report.
* #242: Empty string values in task CLI args now parse correctly. Thanks to
Aaron Levy for the catch + patch.

Documentation updates

* #239: Fixed typo in execution usage docs. Thanks to Pradeep Gowda and Turicas
for the catch.

0.9.2
=====

Feature additions

* The reboot operation has been added, providing a way for Fabric to issue a
reboot command and then reconnect after the system has restarted.
* python setup.py test now runs Fabric?s test suite (provided you have all the
prerequisites from the requirements.txt installed). Thanks to Eric Holscher for
 the patch.
* Added functionality for loading fabfiles which are Python packages
 (directories) instead of just modules (single files.) See Fabfile discovery.
* Added output lines informing the user of which tasks are being executed (e.g.
[myserver] Executing task 'foo'.)
* Added support for lazy (callable) role definition values in env.roledefs.
* Added contrib.django module with basic Django integration.
* env.local_user was added, providing easy and permanent access to the local
 system username, even if an alternate remote username has been specified.
* #29: Added support for arbitrary command-line-driven anonymous tasks via
fab [options] -- [shell command]. See Arbitrary remote shell commands.
* #52: Full tracebacks during aborts are now displayed if the user has opted to
 see debug-level output.
* #101: Added colors module with basic color output support. (#101 is still
 open: we plan to leverage the new module in Fabric?s own output in the future.)
* #137: Commas used to separate per-task arguments may now be escaped with a
 backslash. Thanks to Erich Heine for the patch.
* #144: hosts (and roles) will now expand a single, iterable argument instead of
 requiring one to use e.g. @hosts(*iterable).
* #151: Added a puts utility function, which allows greater control over
fabfile-generated (as opposed to Fabric-generated) output. Also added fastprint,
an alias to puts allowing for convenient unbuffered, non-newline-terminated
printing.
* #208: Users rolling their own shell completion or who otherwise find
themselves performing text manipulation on the output of --list may now use
--shortlist to get a plain, newline-separated list of task names.

Bugfixes
* The interactive ?what host to connect to?? prompt now correctly updates the
appropriate environment variables (hostname, username, port) based on user input.
* Fixed a bug where Fabric?s own internal fabfile would pre-empt the user?s
fabfile due to a PYTHONPATH order issue. User fabfiles are now always loaded at
 the front of the PYTHONPATH during import.
* Disabled some DeprecationWarnings thrown by Paramiko when that library is
imported into Fabric under Python 2.6.
* #44, #63: Modified rsync_project to honor the SSH port and identity file
 settings. Thanks to Mitch Matuson and Morgan Goose.
* #123: Removed Cygwin from the ?are we on Windows? test; now, only Python
 installs whose sys.platform says 'win32' will use Windows-only code paths
(e.g. importing of pywin32).

Documentation updates
* Added a few new items to the FAQ.
* #173: Simple but rather embarrassing typo fix in README. Thanks to Ted Nyman
 for the catch.
* #194: Added a note to the install docs about a possible edge case some
 Windows 64-bit Python users may encounter.
* #216: Overhauled the process backgrounding FAQ to include additional
techniques and be more holistic.

Packaging updates
* #86, #158: Removed the bundled Paramiko 1.7.4 and updated the setup.py to
require Paramiko >=1.7.6. This lets us skip the known-buggy Paramiko 1.7.5 while
 getting some much needed bugfixes in Paramiko 1.7.6.
