Log Message:
Refactor TransactionComponent so that 'txnSvc' can be assigned at __init__.
'joinedTxn' is now the way to require that the component is in a
transaction; 'txnSvc' is just the transaction service, and is now provided
to subobjects, so they needn't search higher in the hierarchy, and so that
a 'txnSvc' override will propagate downwards.  Also, added synonyms:

 storage.begin()  == storage.beginTransaction()
 storage.commit() == storage.commitTransaction()
 storage.abort()  == storage.abortTransaction()

For ease of use in short scripts, etc.  The longer names are still the
"official" names, however, and will show up in tracebacks/help/etc.
