Fix 19916. Smarter tokenizing of contrib.comment's templatetags arguments.
Added a ManyToManyField(db_constraint=False) option, this allows not creating constraints on the intermediary models.
Adde two "versionadded" markers, thanks to mYk for noticing.

Merge pull request #892 from JonLoy/ticket_20018

Fixed #20018: Added backtick to fix reference
Made (make|compile)messages check for availability of gettext commands.

Refs #19584.
Fixed #20019 -- Ensured HttpRequest.resolver_match always exists.

Obviously it isn't set until the URL is resolved.
Moved a warning in the 1.6 notes back to its expected location.
Made transaction.managed a no-op and deprecated it.

enter_transaction_management() was nearly always followed by managed().

In three places it wasn't, but they will all be refactored eventually.
The "forced" keyword argument avoids introducing behavior changes until
then.

This is mostly backwards-compatible, except, of course, for managed
itself. There's a minor difference in _enter_transaction_management:
the top self.transaction_state now contains the new 'managed' state
rather than the previous one. Django doesn't access
self.transaction_state in _enter_transaction_management.
