autoload property for functions from contrib packages

Hi all,

following a proposal by Robert Dodier I intend to add the autoload property to some 
functions from packages in share/contrib. 

Proposed are functions from numericalio, linearalgebra and stringproc. The function names 
are listed below. 
( I am not going to include functions with names which are already in src. These have to be 
loaded manually. )

Any comments, wishes?
