logentries configure.rb does not allow filenames with dash '-'

[pduey]

In configure.rb, the regex is matching the filename part of the path on (\w+.log). \w does not match on dash (and many other valid filename characters). My workaround is to rename my files with _.

Not sure the script needs to be fixed. Maybe just update the README in custom-le to indicate that? Unless the log file is being written by some 3 party code and it's hard to change. But that seems unlikely.
