[autotest] Adds chrome version strings to autofiled bugs.

The reporting module now queries client job keyvals for
the chrome version string and includes it in the summary
of every autofiled bug.This change also fortifies the
reporting module against xml parser syntax errors,
fixes unittest, modifies the default link we use to
point to the buildbot stages, and embeds links to bugs
filed in the buildbot report.

TEST=Ran a suite and tried different permutations of
     aborted tests to make sure we don't crash. Filed
     bugs and checked the format of the version string.
     Ran unittests. Ran run_suite and checked the STEP
     LINKS in the report.
BUG=None
