[LDCad] Aligning parts using rotation scripts

[Roland Melkert]

LDCAD does not allow neither user nor scripts work with snap objects, AFAIK. (And as I remember past conversations with Roland,it is not easy to implement in current LDCAD code.)

It is actually partial available in LDCad 1.6 (a leftover from my experiments which I forgot to remove).
The current 1.7 version has it all commented out, but I might put it back in again when picking 1.7 development up in my coming vacation.

Another improvement is using current coordination system instead of the global one. To make script works for setups rotated in any way - just select a part, press "O" to get local coordination system, and continue with the script as usual.

This is something I can easily add, so I will add it to the ldc.view ( http://www.melkert.net/LDCad/docs/scriptAPI2#view ) object in the upcoming version.

It will only return the current matrix, as the LDCad api is supposed to be (very) low level only.
