skypopen: changed definition of SKYPOPEN_SVN_VERSION in Makefile.am, because the present one does not works with the git output

* 'master' of git.freeswitch.org:freeswitch:
  The .version file should die on a git pull.
  Skinny: Hook the proper line
  Skinny: unused variable
  Skinny: security

- Avoid writing outside of fields
- tab ident

- Correct Skinny-Station-Instance event header and log if profile or
  device is not found

also, use tab to indent
