ref-filter: include reference to 'used_atom' within 'atom_value'

Browse Source 
Ensure that each 'atom_value' has a reference to its corresponding
'used_atom'. This lets us use values within 'used_atom' in the
'handler' function.

Hence we can get the %(align) atom's parameters directly from the
'used_atom' therefore removing the necessity of passing %(align) atom's
parameters to 'atom_value'.

This also acts as a preparatory patch for the upcoming patch where we
introduce %(if:equals=) and %(if:notequals=).
