rewrote parts of trell-master-job-starting to use apr
moved TINIA_APP_ROOT to environment variable instead of argument
moved args needed to set up cloud jobs to env, next step is to use them in cloud jobs
Updated mod_trell-poke to send arguments to jobs (as well as some other
small fixes).
Commented out some of the very verbose debug logging.
Updated XML schema to allow for addjob application arguments.
Arguments are now part of job's book-kept state.
Use tinia config passed as env variables instead of arguments. Passing
of arguments throughout system seems to work.
Removed obsolete copying and passing of addjob-xml (arguments are now
passed directly via argv).
Removed pass-through of tinia-variables when executing a job, as these
variables are explicitly set.
