Add a storm/psycopg2 recipe

[romaia]

This should allow using python-storm (https://storm.canonical.com/) and
psycopg2 for connecting to a postgresql database.

This is currently building but not working.

Storm depends on psycopg2, and psycopg2 depends on libpq. I have managed to build all of them and install on android, but when I try to use psycopg2 I get the following error:

I/python (28229): Traceback (most recent call last):
I/python (28229): File "/home/romaia/devel/kivy/.buildozer/android/app/main.py", line 176, in

I/python (28229): ImportError: dlopen failed: could not load library "libpq.so.5" needed by "_psycopg.so"; caused by library "libpq.so.5" not found

Obviously, libpq.so is missing in the generated apk, but I don't know how I can tell py4a to include it.

Update: I did manage to build by statically compiling the libraries. An update to the patch will follow. If some could also review them I would appreciate

Looking good, thanks!
