keyword=HAPPEX DAQ to "safe" mode

There was some evidence that someone was accidently deleting object
files for libraries needed by the HAPPEX DAQ. This leads to failures
which were not obvious to newbies. And this disappearance happened
to me a couple times before the experiment, too.

To make things safer, I've copied the object files to ~apar/daqfiles.
The boot scripts for the L-HRS and Counting room crates are
now, respectively, happex7_safe.boot and halladaq6_safe.boot.

To back out of this, use the old happex7.boot and halladaq6.boot
(those are unmodified).

Additional notes:

1. I did not copy the compiled CRL codes. This would have required
modifying the CODA database to point there, but it seemed unecessary
because a) no evidence those were getting deleted, and b) if CODA
does not download, one sees clear error messages. So, then you
must re-makelist them or page an expert. (The problem with other stuff
missing is that it's typically harder to decipher.)

2. I did not touch the Lumi stuff. Joe may continue as before,
except note that happex7_safe.boot is used.

3. I did not modify happex4 (TS) boot. It is already safe enough.
