[LDCad] Aligning parts using rotation scripts

[Roland Melkert]

Installation: put axis.dat in your directory with unofficial parts and rename shadow_axis.dat as axis.dat in your directory with unofficial shadow files, as set in your LDCAD configuration.

It being an unofficial helper part, you can also put the snap meta's in the part itself (no shadow needed).

LDCad processes parts as a single file after appending the shadow content to it.
