closes #929

rationale: proper build needs to go through setup.py anyhow
by renaming Makefile to a less common name, we avoid people building by mistakes
only the makefile-driven part.

This also helps distribution heuristics when guessing how to auto-build
packages (e.g. Debian dh_auto_build)

This allows using ./setup.py --url as long as you ignore stderr, for example.

This allows running "make clean", or "make all" without using the
setup.py.

I don't think other distributions use the old naming. Also removing 2.5.

When make is missing, setup.py prints a message suggesting to install
PyQt4-devel even if it already is. This change with the help of
6788c11a6d63824862d340f82da9de46ef63ee60 makes the message more helpful.

Before:
$ python setup.py
Building Qt applications
Install PyQt4-devel or disable Qt applications (with --no-qt).

After:
$ python setup.py
Building Qt applications
Could not find executable: make
Install missing component(s) (see above) or disable Qt applications (with --no-qt).

The error message is sometimes confusing. Consider the following
situation on Debian 6.0:

$ python setup.py
Building Qt applications
Install PyQt4-devel or disable Qt applications (with --no-qt).
$ dpkg -l | grep -i python | grep -i qt
ii  python-qt4          4.7.3-1+b1         Python bindings for Qt4
ii  python-qt4-dev      4.7.3-1            Development files for PyQt4

What is really missing is the pyuic4 executable which is provided by
a different package on that distribution. But you have no way to know
that unless you go look into setup.py. This change prints what
executable we are missing as to help diagnose this kind of problem:

$ python setup.py
Building Qt applications
Could not find executable: pyuic4
Install PyQt4-devel or disable Qt applications (with --no-qt).

Notice that until e69adf35

,
the name of the missing executable was printed as well.

This should force Python 2 on Gentoo (though it worked with default
config), and work again with Arch.
The find_executable() function should work on POSIX and Windows
platforms.
It is also easily possible to override executables.
Generally the code is shorter and PEP8 compliant.
