Filtering does not recognize quantities

[mdenker]

In this example, t_start is filtered to be 0, but the t_start is actually 0 seconds. Thus, the unit is ignored. Is this behavior desireable (i.e., if not unit is passed when filtering a quantity, assume the unit of the property/annotation?

h=bl.filter({'t_start':0})
print len(h)
print h[0]
# This is 0 seconds, not 0
print h[0].t_start

This is what I get from running of above code:

print len(h)  # 30
print h[0]     # [ 0.01  3.3   9.3 ] uV
print h[0].t_start   # 0.0 s

The quantities is also included in output. What went wrong here, I'm not sure that I got it.
