Update sysutils/fabric to 1.4.3

Upstream changes:

2012-07-06: released Fabric 1.4.3
2012-07-06: released Fabric 1.3.8

[Bug] #671: reject_unknown_hosts sometimes resulted in a password prompt
instead of an abort. This has been fixed. Thanks to Roy Smith for the report.

[Bug] #659: Update docs to reflect that local currently honors env.path. Thanks
to @floledermann for the catch.

[Bug] #652: Show available commands when aborting on invalid command names.

[Support] #651: Added note about nesting with statements on Python 2.6+. Thanks
to Jens Rantil for the patch.

[Bug] #649: Don?t swallow non-abort-driven exceptions in parallel mode. Fabric
correctly printed such exceptions, and returned them from execute, but did not
actually cause the child or parent processes to halt with a nonzero status.
This has been fixed. execute now also honors env.warn_only so users may still
opt to call it by hand and inspect the returned exceptions, instead of
encountering a hard stop. Thanks to Matt Robenolt for the catch.

[Support] #645: Update Sphinx docs to work well when run out of a source
tarball as opposed to a Git checkout. Thanks again to @Arfrever for the catch.

[Support] #640: (also #644) Update packaging manifest so sdist tarballs include
all necessary test & doc files. Thanks to Mike Gilbert and @Arfrever for catch
& patch.

[Support] #634: Clarified that lcd does no special handling re: the user?s
current working directory, and thus relative paths given to it will be relative
to os.getcwd(). Thanks to @techtonik for the catch.
