fix pear info for packaging
pear: add options for bin_dir, php_bin, and php_dir settings

packages with executables will put their bins in bin_dir, which is
prefix/pear by default. php_bin can be used if the php interpreter is
in a different location on the target system. php_dir can be used for
overriding the directory where php files are put (useful on debian).
pear: remove debug statement
pear: add more unnecessary pear directories to delete
pear: replace pear_path in executable files

some packages put the pear_path value in their executable (PHPUnit for example)
which is the staging path, so it has to be replaced to the installed path, otherwise
the executable won't work

- Try to set a sane default path if you specify --prefix for python
  packages.
  If you say --prefix /foo/bar, then setup.py is invoked with:
    .py --install-data /foo/bar/data
    .py --install-scripts /foo/bar/bin
    .py --install-lib /foo/bar/lib

Pear enhancements
- escape the staging_path in a regexp when replacing the pear_dir paths
- Folks gettin' angry about an abandoned prototype they mistook for
  functioning and supported code, so let's delete this 'fpm-npm'
  hackery. Someone will write proper npm package support for fpm
  eventually.
