Using jquery.autocomplete plugin if you 'autocomplete' on a value of '0' the first element from the data-cache array is returned even if that element does not contain a '0'.

This seems to be happening in the 'loadFromCache' function:

if (cache.data[q]) return cache.data[q];

If q is 0 it appears to be returning the first element of cache.data.

The following change fixes this, however I am not sure if it is the best solution:

if (q != 0 && cache.data[q]) return cache.data[q];
