Add /logs to webserver view and add more extensions to text/plain ForceType.

Add /logs as an alias on the webserver so that all autotest scheduler and
run suite logs are exposed via the webserver frontend.

Force all log extensions like .DEBUG, .WARNING, .INFO to be interpreted
as txt.

BUG=chromium-os:32581
