nose 0.8.7 released

[JP]

This release has a few new features and a few more bugfixes.

CHANGELOG:

- Add support for py.test-style test generators. Thanks to Jay Parlar
for the suggestion.

- Fix bug in doctest discovery. Thanks to Richard Cooper for the bug
report.

- Fix bug in output capture being appended to later exceptions. Thanks
to Titus Brown for the patch that uncovered the bug.

- Fix bug(?) in Exception patch that caused masked hasattr/__getattr__
loops to either become actual infinite loops, or at least take so long
to finally error out that they might as well be infinite.

- Add -m option to restrict test running to only tests in a particular
package or module. Like the -f option, -m does not restrict test
*loading*, only test *execution*.

- When loading and running a test module, ensure that the module's path
is in sys.path for the duration of the run, not just while importing
the module.

- Add id() method to all callable test classes, for greater unittest
compatibility.

Barring show-stopping bugs, this will be the last release before the
plugin-tastic version 0.9.
