1.4.0.2 / 2012-06-20

Bookkeeping release that fixes install in scenarios where the RubyGem indicated it had a runtime dependency on hoe. Thanks to Michael Grosser (github.com/grosser) for the inspiration.
Marked all files as UTF-8.

Adding a post-rewind hook (#_post_transaction_rewind) so that complex graph objects can correct themselves after rewinding. See the documentation for rewind_transaction and tests/tc_broken_graph.rb for more information.
Removed all warnings.
Deprecated the transaction method.
Various administrative changes:
- Converted to a hoe-driven project.
- Made the gem and .tar.gz files idempotent.
- Cleaned up the code a little further.
- Changed non-gem installer to setup.rb version 3.4.1.

Explicitly clearing the transaction checkpoint on objects when the last open transaction is committed or aborted.
Fixed up behaviour to remove a lot of respond_to? calls.

Updated to fix a lot of warnings.
Added a per-transaction-object list of excluded instance variables.
Moved Transaction::simple::ThreadSafe to transaction/simple/threadsafe.
Added transaction groups. Transaction groups are wrapper objects to allow the coordination of transactions with a group of objects. There are both normal and threadsafe versions of transaction groups.
Fixed a long-standing problem where instance variables that were added to an object after a transaction was started would remain.
Reorganised unit tests.

Added Transaction::Simple::ThreadSafe for truly atomic and thread-safe transactions.
Fixed the description of Transaction::Simple to note that it is not atomic because it is not implicitly thread-safe.
Added support for named transactions. Named transactions can be used to make checkpoints that can be committed, aborted, or rewound without explicitly committing, aborting, or rewinding the intervening transactions.
