- logs go into $GL_ADMINDIR/logs by default, named by year-month
- logfile name template (including dir prefix) now in $GL_LOGT
- two new env vars passed down: GL_TS and GL_LOG (timestamp, logfilename)
- log messages timestamps more compact, fields tab-delimited
- old and new SHAs cut to 14 characters
system("...") run from perl on sol does not seem to like "~" (regardless of
what $SHELL is set to), so use $ENV{HOME} instead

In the "create new repos" loop, we need an absolute value for REPO_BASE, in
order to be able to chdir back and forth. But (taking the "normal user with
no privileges" assumption too far!) we assumed REPO_BASE would be within
$HOME, and relative to it. So it fails when someone wants the repo_base
elsewhere.
Now we don't prefix $HOME if REPO_BASE is already absolute (begins with a "/")
