Fix Issue #2148: loadups fail on WSL1 with Xvnc server errors - fixed by adding new flag to medley script, use this flag in loadup script (#2163)

* Fix Issue #2155 (loadup -f -b -x fails can't find full.sysout).  Reordered loadup so that the sysouts are copied to loadups before loadup-aux and loadup-db are run, and that the product of loadup-aux are copied to loadups before loadup-db is run -- all to make sure that the right prerequisites are available in loadups when needed.  Also forced a run of loadup-aux if full.sysout is newer than exports.all when -db is specified.

* Fix Issue 2148 - loadups fail on WSL1 with Xvnc server error.  Root cause of 2148 is that certain Medley sessions in loadups run very quickly - less that a second or 2.  This causes the medley script to improperly detect an Xvnc server error.  Fixed by adding a cli flag --automation that forces the medley script to skip the check for Xvnc server errors.  Changed loadup script to call medley with this flag set.  Also add a cl flag to loadup --forcevnc that forces loadup to use vnc even on WSL2.  This is intended for testing purposes only.
