[PD] load abbreviated objects

[Georg Holzmann]

Hallo!

First: do you use the autobuilds or the "stable" pd-extended ?

Because the hexloader was broken - I don't know if this is already fixed 
in the autobuilds ...

I once included all the iemmatrix objects and also it's aliases. They 
should be in the nightly autobuild version, although I don't know if the 
hexloader works (at least it should work with mtx_add, mtx_div, ...).
However, I don't think that they should be loaded by default, but that's 
an other discussion ... ;)
