flake8: fix imports, flake8 reported the following: templating.py:25:1: F401 'base64' imported but unused templating.py:25:1: F401 'mimetypes' imported but unused templating.py:25:1: F401 'string' imported but unused templating.py:28:1: F401 'time' imported but unused templating.py:28:1: F401 'hashlib' imported but unused templating.py:34:1: F401 'roundup.i18n' imported but unused templating.py:35:1: F401 'roundup.i18n._' imported but unused templating.py:36:1: F401 'roundup.anypy.strings.b2s' imported but unused templating.py:36:1: F401 'roundup.anypy.strings.s2b' imported but unused templating.py:43:1: F401 'roundup.anypy.random_' imported but unused templating.py:47:5: F401 'pickle' imported but unused Turns out time import was used by test_templating via from roundup.cgi.templating import * so added import time to test_templating Also split out multiple imports on one line into sepearate lines. Changed todo = to __todo__ to make flake8 shut up about module level imports not at top of file. Moved definiton of _disable_url_schemes for same reason.

A number of tests uses the infrastructure of
	db_test_base.py

grep "from db_test_base" -l *.py
benchmark.py
session_common.py
test_anydbm.py
test_indexer.py
test_memorydb.py
test_mysql.py
test_postgresql.py
test_security.py
test_sqlite.py
test_userauditor.py

grep "import db_test_base" -l *.py
test_cgi.py
test_jinja2.py
test_mailgw.py
test_xmlrpc.py

grep "import memory\|from memory" -l *.py 
test_mailgw.py
test_memorydb.py


The remaining lines are an 2001 description from Richard,
which probably is outdated:
