Removed RunModule.py.

Modules can be run with Python's -m option, so RunModule.py is
unneccessary.
Moved remaining scripts into pywws package.
Do Python 3 translation during build.

This is the 'approved' way of supporting Python 3, using distutils to do
the 2to3 translation during its 'build' processing.
Moved contents of 'code' directory to top level.
Updated documentation.

The changes are purely to make the documentation compilable, not to make
it correct!
Don't delete html redirect in 'make clean'.
Added convenience scripts.

These two scripts allow pywws.Hourly and pywws.LiveLog to be run from
anywhere, and without typing 'python -m pywws.xxx'. They get installed
to standard directories by setup.py, so can easily be called from cron
jobs and the like without having to set $PATH.
Moved example templates and scripts.
Install example files.

The example templates and module will now be installed by setup.py,
typically in /usr/share/pywws or /usr/local/share/pywws.
Updated documentation.

Changed the first page and getting started guide to reflect the
rearranged file structure. Expanded the getting started guide to include
more about the different download and installation options.
Updated documentation.
Updated documentation.
Removed documentation references to RunModule.py
Moved creation of version file.

Instead of using 'make' to generate pywws/version.py with 'constants'
in it, it's now a Python module that sets the version numbers when it's
imported.
Get commit of current branch, not 'master'.
Improved setup.py.

Moved some config from setup.cfg into setup.py.
Added a distutils command to 'compile' the language files (i.e. generate
.mo files from the .po text sources). This was previously done in the
makefile.
Fixed documentation of wunderground URL.
Moved translation stuff from makefile to setup.py

Still need to update documentation to reflect new way of doing things.
Further changes to language file building.

The .mo files compiled from .po language files are now created directly
in pywws/locale. This removes the last essential stage from the make
file, which can now be discarded.
Updated translation user guide.
