MDL-34704 couse, accesslib: improve $CFG->courselistshortnames

1. get_context_name should respect the $CFG->courselistshortnames
setting.

2. When $CFG->courselistshortnames is on, what to display should use a
language string, rather than string concatenation. This makes it
possible for people to configure the display. For example, they might
want 'My first course [M101]' instead of 'M101 My first course'.
