Added Shane's warning re. not using the ZODB to docstring.

- synced sha-bang with other scripts

Still show the directory, though.

Apply patch by Josh LaPlace. Makes DAV 'supportedlock' actually check if the object implements the WriteLockInterface.

There are no tests for this code, but the branch was tested by using
it for releases of some Zope Corp. products.

Merge chrism-publishfile-branch.  See http://dev.zope.org/Wikis/DevSite/Proposals/FasterStaticContentServing for more information.

om loss of valid results in high-concurrency situations. This problem is especially bad for applications (like CMF) that rely on catalog results as a way to get
 a list of objects to act on.

refactoring: many methods contained duplicated code from dispatch().
also broke dispatch up into multiple lines for easier reading/debugging.

when calling manage_reindexIndex() from script code but not TTW.

App.config.setConfiguration() did not update the legacy source for debug_mode, Globals.DevelopmentMode.

    don't test any of that here.)

  - include a test suite declaration

  - slight clarification on some of the test names and content ids

(distutils mungs it anyway, so it's just relevant for developers)

Special Users and security managers that return None objects should not play.

_setObject method.

Specifically the key for 'Owner' local role should be the user's Id,
not UserName

Tests this behavior with six combinations:

  'None' security manager attempting to set ownership
  'Emergency User' security manager attempting to set ownership
  'System User' security manager attempting to set ownership
  'Anonymous User' security manager attempting to set ownership
  'User' security manager attempting to set ownership
  'Faux User' security manager attempting to set ownership

  'None' security manager not attempting to set ownership
  'Emergency User' security manager not attempting to set ownership
  'System User' security manager not attempting to set ownership
  'Anonymous User' security manager not attempting to set ownership
  'User' security manager not attempting to set ownership
  'Faux User' security manager not attempting to set ownership

when external user folders can specify a difference.

Uniform handling of errors is get_suite() allows this code to be
simplified.

Add docstring that explains rules for finding tests.
Reflow some paragraphs.

Remove 'python2.2' and 'python2.1' as acceptable executable names, as we're only interested in working under 2.3 now.

Python 2.2.3 and older are no longer acceptable versions of Python to use to run Zope 2.7+, as the logging package was removed from Zope proper and Zope requires it to start up.  The logging package exists in Python 2.3 and better.

Script (Python) objects now have a _filepath attribute, also used as the '__file__' global at runtime.  This prevents an import problem caused by the fix to #1074.
