Bump version to 2.6.3.

Update copyright year.

Makefile: Add target `install`.

This makes distribution packagers live even easier.

Makefile: Add target `dist`.

Update .hgignore.

Add a README.

Add setup.py, setup.cfg and MANIFEST.in.

docs: Include files are always searched at standard location, too.

This removes the need to specify the location where yml2 was unpacked or
installed as YML_PATH. So this now works:

YML_PATH=/foo ./yml2proc --xml2yml

The standard system location <prefix>/share/yml2 is now always appended to
the include search path. If this path does not exist, the directory one
above the `backend.py` file is added, allowing the same behaviour for
uninstalled yml2.

In the Makefile enforce the .ysl2 files to be searched in the current
directory first.

Move data files into the Python package.

The packe directory is now always searched for include files, after
all other directoreis given in $YML_PATH.

Catch missing xml2yml.ysl2 early.

Convert yml2 into a Python package.

* Rename yml2.py -> yml2/__init__.py
* Rename backend.py -> yml2/backend.py
* Rename pyPEG.py -> yml2/pyPEG.py
* Use relative imports where appropriate.
* Change imports in yml2c, yml2proc.
* Update make target `clean`.
