Added some support for the open PDKs in the technology manager GUI. 

This uses environment variable PDK_ROOT to search for available
technologies, and loads them by sourcing the .magicrc file instead
of using "tech load".  However, there are currently some caveats:
(1) The device generators do not immediately appear in the window
menu;  a new window must be created for the extra menu buttons to
be added;  (2) Once a PDK sets up the menus, they cannot be
revised.  Switching to another technology causes the extra menu
items to not appear at all.  Both issues need to be addressed.
