Merge lp:~qsantos/duplicity/fix-unmatched-rule-error into lp:~duplicity-team/duplicity/0.8-series

[qsantos]

There are actually two commits: the first fixes a very minor detail in the README regarding the Python version that should be used; the second fixes the way exceptions are handled when an incorrect rule is specified, and display the nice error message rather than an obscure stack trace.
