The Axe list

Folks,

It's that time again!  Purging antiquated contrib modules.

chkpass: this module is incomplete and does not implement all functions 
it describes.  It's not really even useful as an Example since it uses 
crypt() and not any modern encryption.  And Darcy hasn't touched it in 6 
years.

intagg: the aggregation function has been obsolete since 7.4 because 
standard array functionality supports the same.  intagg has a nice 
equivalent for UNROLL, but it only works for arrays of INT, and only 
one-dimensional arrays.  Has not been updated since 2001.

Any objections to dropping both of these?
