can.compute evaluations for the default Mustache handlers
insert mapped list items at the correct index

Line 90 says: // The indices in the mapped list are the same so lets just splice it out

Which is wrong without this fix, as items are always added to the end of the list.
Added compute check for context objects when resolving object references in mustache.
Tests for compute checks for the various default helpers
Fixing can.ajax for Mootools

- onError is only for JSON parsing errors, Ajax communication errors are
in onFailure
- do not clobber mootools native onSuccess and onFailure if passed in
- remove local JSON parsin and use Mootools for it
