Improve arc compatibility on Windows

Summary:
  - When altering the include_path(), use PATH_SEPARATOR (";" on Windows, ":" elsewhere) instead of hard-coded ":".
  - Detect missing php_curl.dll extension.
  - Use APPDATA instead of HOME for storing .arcrc (the internet implies this is correct?)
  - Don't try to do chmod() stuff on Windows; it's not critical and I don't want to figure out how it works.

Test Plan: Was able to run part of some arc commands on Windows.
