Labels apply pre-alignment

[GoogleCodeExporter]

In code like this:
    org
y   byte 1
x  long 2

The label 'y' will be on byte 0, and the label 'x' will be on byte 1 -- even 
though the long it 
presumably labels is aligned to byte 4.

I'm not entirely certain if I consider this a bug -- there are cases where this 
behavior is desired:

data_start
   byte 1
   byte 2
   byte 3
data_end

  long 0

Since propasm doesn't care if a label is on the same line as a value or a 
separate line, these cases 
are identical.
