Fix counts in multi-dimensional charts

Whenever the second sort field changes, we need to change
its nonblank counterpart accordingly, otherwise we'd be
updating incorrect value in the 'counts' hash. That would
lead to incorrect charting numbers being returned by
the build_reporting_chart_dim2() method.

#1182
Replaced ajax calls from prototype to jquery.

- Replaced occurrences of Ajax.Request to $j.ajax
- Changed default type for ajax calls to be "POST", this was "GET" by default.
- Changed occurrences or "Parameters" on ajax calls to "data", jquery expects "data" to be present that it uses to convert to a querystring and send it upto the server.
- Changed miq_dhtmlxtoolbar.js to strip out "?" from the params that is the first character in the button.url_parms string, jquery expects data to be a key/value pair.

add the original exception's backtrace when raising

just raising an exception with the string will lose the backtrace of the
original exception.  This patch adds the backtrace from the original
