EDE Security & Config files update

Greetings,

I've continued to update EDE in the CEDET/BZR repository.  The latest 
update includes tests for EDE's security system that prevents lisp code 
(the EDE config files) from loading without asking.

Feature wise, the main change is that generic projects are now 
considered safe, and will be automatically created w/out loading of the 
config files.  If you customize a generic project, it will then ask to 
be added to the safe projects list.  If you download someone else's 
project that has a config, it will ignore it until you try to do an 
action that needs the config file, and then it will ask.  There are 
tests to keep this working which were previously lacking.

I've also made the config file handling into a utility, and the arduino 
project type now has its own config file so you can have some sketches 
for one kind of board, and other projects for a different board.  Folks 
who have a favorite project type that could benefit from a config file 
should have an easy time of getting a safe config feature working now.

Please let me know if you run into any problems with these new changes.

Thanks
Eric
