Symphony Availability may return a 200 but still contain an error

[ruthtillman]

This morning we had an availability error with 200 response but content:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Fault xmlns="http://schemas.sirsidynix.com/rest"><code>java.lang.NullPointerException</code></Fault>`

So ... I guess we need to test for the Fault element and then a) display the error message / b) log the error (or maybe @whereismyjetpack's side will take care of that logging when it leaves Symphony?)

Question: is this true of other WebService calls and do we have any others that we might need to handle? Thinking of My Account but unsure what that'd look like until we see it.
