0023185: DrawAppliInit must be loaded from current directory

1. File src/DrawResources/DrawAppliInit removed;
   code loading QA commands moved from DrawAppliInit to DrawDefaults (temporarily)

2. In src/DrawResources/DrawDefaults:
   - change of tcl_precision removed (following advise in Tcl 8.5 documentation)
   - code loading file init.tcl removed as obsolete
   - if environment variable CSF_DrawAppliInit is defined, it is assumed to
     be the name of the application-defined file to load; otherwise
     it is searched as file DrawAppliInit in current directory
