improve Automater invocation

[evilscheme]

Hi, this little patch makes Automater a bit more pleasant to use:

---

diff --git a/Automater.py b/Automater.py
old mode 100644
new mode 100755
index fa7ee84..0906414
--- a/Automater.py
+++ b/Automater.py
@@ -1,4 +1,4 @@
-#!/usr/bin/python
+#!/usr/bin/env python

import httplib2, re, sys, argparse, urllib, urllib2

Uses /usr/bin/env python (allows for non-standard python installs), and sets the file mode to 755 so you can run ./Automater.py
