[BLAST_ANAWARE] timing, trigger bug and tdc offsets

Hello,
I've found a bug in the trigger gui. Depending on how the file is
downloaded the CFD retime delays are actually not updated (note their
are not necessarily zeroed). You have to do download form each delay
window (download all or trig -d don't do it). It seems a software problem.

The problem could have been there since last year. There are two
consequences for our data, but probably not terrible:

 _ the Wch may have not been always retimed (to the tune of a few ns, 20
   ns max) which is an issue for resolutions.

 - The Tof timing corrections may not have been applicable since they
   somehow "contained" this delay (this is a separate issue and hopefully
   is solved differently)
