changing the python default from 2.6 to 2.7

2.7 is now the default python version in natty. packages were rebuilt and
should be upgradable (except a handful, like ethos and xen-3.3). "Upgradable"
doesn't mean that everything already works with 2.7, so please report issues and
tag these with `python27'. The next step will be to identify all the packages
only depending on libpython2.6 or python2.6 (but not 2.7) and rebuild/upgrade
these to python2.7.
UPGRADE ISSUES: When upgrading from Ubuntu 10.10 (maverick), please make sure
to upgrade to maverick-updates first, before upgrading to natty. If you are
upgrading directly from maverick or from an earlier natty snapshot, and are
stuck, please see comment #5 in bug #689306 .
