Add a integration test suite and fix a signal connect bug when attaching reports

Summary:

• Fix radios' updating UI as they are toggling not buttonclicking :(
• add a cmdline option to enable bringing up the dialog directly. in a testing scenario it makes sense to skip the notification popup thing and go directly to the dialog
• new env var DRKONQI_KDE_BUGZILLA_URL to override the bugzilla url. for testing purposes we'll want to change the bugzilla url to point to a double instance but otherwise not impact functionality of drkonqi
• new env var DRKONQI_IGNORE_QUALITY to bypass trace quality checks. during testing a proper trace may not be creatable, setting the env var allows bypassing the quality constraints
• set a11y names on text inputs to facilitate a11y enablement (also allows finding them through at-spi for testing purposes ;))

add an integration test based on xvfb+dbus+at-spi

• suite wrapper program isolates the environment a bit, starts a xvfb instance and runs a session bus inside, then starts the actual tests from inside the isolated environment
• duplicate_attach_test.rb starts an xmlrpc server, a defunct ruby, and a drkonqi to trace the defunct ruby. it then uses at-spi to massage the drkoknqi GUI into attaching a new trace to a bug via xmlrpc server.
• the xmlrpc server partially falls through to bugstest.kde.org but mostly doubles for bugzilla

fix a connect bug when attaching a new trace to an existing report

Test Plan:
make test should™ run the integration test assuming requirements are met (ruby+atspi+xmlrpc+xvfb-run).

XEPHYR=1 make test will run the test through xephyr rather than xvfb, which is somewhat more useful for test writing and debugging.
