Put the fault detection functions (getStatus and faultCheck) in try...catch blocks. Fixes #135

Should reduce the chances of a silent crash
They should give a fault 'pip' instead of crashing.
Not easy to test though becasue crashes are so rare...
Use git diff -w to show the real changes, otherwise this looks like a huge change.
