Use ActionView::OutputBuffer#safe_append= from templates
avoid extra method calls for appending newlines

Exception handling for controllers using ActionController::Live

Any exceptions that occured at the view or controller level for a
controller using ActionController::Live would cause the server to either
hang with an open socket indefinitely, or immediately crash (depending
on whether the server was launched with rails s or directly). Changed
the behavior of exceptions to act the same as streaming templates for
html requests, and allow for an on_error callback if needed.

ensure the schema checking is done in the dev connection
default task should also be in the test env
switch to Rails::TestTask
a test file can be provided to rake, e.g.:

  rake test path/to/test.rb
switch the testing tests to use rake
test no longer makes sense after requiring all test files
only match the default task
check pending migrations against the test db
