prevent creation of SQLAlchemy-migrate table when initializing a new database
fix initial DB creation using 'paster setup-app deployment.ini'.

The "websetup()" will configure a custom version table after running env.py but without this fix alembic will fail before as it tries to validate a table name 'None'.
ignore missing 'external_template' key in config file
feed links are now added in controller functions to reduce the crazy Genshi py:match stuff
reorganize imports
set gettext domain in templates to enable proper translation of plugin templates
unify license header for deployment.ini template
