Make view query parameter stale value case insensitive

Testrunner's testsuite py-viewlong.conf is failing because it's passing ?stale=False in a query instead of ?stale=false:

2012-05-04 16:39:59,164 - root - INFO - index query url: http://192.168.1.75:9000/couchBase/default/_design/dev_test_compare_views_all_nodes/_view/dev_test_compare_views_all_nodes?connection_timeout=60000&full_set=true&stale=False
2012-05-04 16:39:59,199 - root - ERROR - http://192.168.1.75:9000/couchBase/default/_design/dev_test_compare_views_all_nodes/_view/dev_test_compare_views_all_nodes?connection_timeout=60000&full_set=true&stale=False error 400 reason: query_parse_error

{"error":"query_parse_error","reason":"stale only available as stale=ok or as stale=update_after"}

This can be made case insensitive.
