create-alias: support multiple alias targets

- support multiple alias targets, patch by anexius@SF,
  http://sourceforge.net/projects/postfixadmin/forums/forum/676076/topic/4004442
  The patch fixes
  https://sourceforge.net/tracker/?func=detail&aid=2706290&group_id=191583&atid=937964

additional small fixes:
- replace spaces only at the start and end of a line, not in the
  middle of an (BTW: invalid) mail address
- allow multiple error messages (separated by <br />
- prevent input data loss on validation errors

(I'll port this to trunk.)
