bug 5378.
lonparmset.pm
- Users allowed to clone course:
  - can use wildcards (*:domain and *) for unrestricted cloning within a domain, and unrestricted cloning in all domains respectively.
  - warning messages about invalid data separated into (a) invlaid format, invalid domain, non-existent user.

loncommon.pm
- cloning rights check accommodates wildcards.
- let the user know the course was not created, when the specified course to clone was non-existent, or cloning rights were missing.

Autocreate.pl
- improve format of logged messages.

batchcreatecourse.pm
- Since loncommon::construct_course() now terminates course creation when cloning rights check is not passed, early out to stop user creation and attempted enrollment in an uncreated course.
