[Patch for 2.4] make "cfg_dir=" ignore hidden files

[Bjoern Beutel]

Hello,

when editing my Nagios configuration using Emacs, I sometimes can't restart Nagios
because it reports an error about an ill-formed .cfg file.

The reason is that Emacs creates a lock for each file that has been changed 
but not yet saved. For example, the lock for "dir/my_file.cfg" is a symbolic link 
named "dir/.#my_file.cfg". When "dir" is included by "cfg_dir=", Nagios tries 
to read the symbolic link, complains and exits. 

The patch below solves the problem by making "cfg_dir=" ignore hidden files.
