PEP 292 classes Template and SafeTemplate are added to the string module.
...
This patch includes test cases and documentation updates, as well as NEWS file
updates.
This patch also updates the sre modules so that they don't import the string
module, breaking direct circular imports.

Improved error msg when a symbolic group name is redefined. Added docs
...
and NEWS. Bugfix candidate? That's a dilemma for Anthony <wink>: /F
did fix a longstanding bug here, but the fix can cause code to raise an
exception that previously worked by accident.

bunch more __all__ lists

also modified check_all function to suppress all warnings since they aren't
relevant to what this test is doing (allows quiet checking of regsub, for
instance)
