fix Makefile chmod (644)
replace MD5SUM with HASH
add PKG_MIRROR_HASH when PKG_SOURCE_PROTO:=git

(PKG_SOURCE_PROTO:=svn tarballs are not reproducible for now)

I admit this may be be a bit aggressive, but the lang
folder is getting cluttered/filled up with Python, PHP, Perl,
Ruby, etc. packages.

Makes sense to try to group them into per-lang folders.

I took the Pythons.

- update to latest version (16.0.0)
- change to one package containing all plugins/subprojects
- add license info
- add myself as maintainer

This builds one main package, instead of multiple packages like the old
packages feed, to match upstream. (Debian and Fedora are moving to a
single-package model as well.) The obvious downside is a larger install
size, but one main package should be easier to maintain in the future.
