Improve split script (#1011)

- Added shebang and made the script executable.
- Added help text.
- Added -o/--out argument for specifying output directory.
- Added -e/--extension argument for specifying file extension of the
  implementation file.
- Made the script find httplib.h next to split.py instead of the current
  working directory. This makes it possible to call the script from
  another directory.
- Simplified code structure slightly.
- Improved variable naming to follow Python conventions.
