Add packaging stuff
Dependency python-lxml added
Use python2-devel instead of python-devel in BuildRequires:
Start summary of lang-table-data with capital letter
Remove unneeded python specific rpm macros
Fix license in headers of .py files

GPLv3+ was intended.
Add “MIT” to License: in .spec file and add a comment to indicate which files are affected

Also edit “License” section in README.
Rename the project from “lang-table” to “langtable”

A “-” does not work in the name of a Python module, i.e. lang-table.py
does not work. Therefore, I used “langtable.py”. But then it
is nicer if the .spec file and the the whole project is als called
just “langtable” for consistency.
Move the .xml files to a data/ folder in the sources
Add “review” target to Makefile for convenient checking of the rpm
