add normalization to beni

[barzerman]

normalization: all characters divide into classes digits, alpha, punctuation and space

• punctuation becomes space
• space between two digits and between two alphas becomes space persists
• all other spaces get thrown out

When indexing we must also add a name without any spaces/punctuations When searching in beni we must try the same (de-punctuate/de-space the input) and add it to results

example RL-50 RRCSW

when someone is looking for RL50RRCSW or RL 50R R CSW they mean to find it.
