* This PR impliments the feature request #784.

When a folder is explicit defined in `pyproject.toml` as excluded, all nested data, including subfolder, are excluded. It is no longer neccessary to use the glob `folder/**/*`

* use `Path` instead of `os.path.join` to create string for globbing

* try to fix linting error

* create glob pattern string by concatenating and not using Path

* using `os.path.isdir()`` for checking of explicit excluded name is a folder, because pathlib's `is_dir()` raises in exception under windows of name contains globing characters

* Remove nested data when wildcards where used.

Steps to do this are:
1. expand any wildcard used
2. if expanded path is a folder append  **/* and expand again

* fix linting

* only glob a second time if path is dir

* implement @sdispater 's suggestion for better readability

* fix glob for windows?

* On Windows, testing if a path with a glob is a directory will raise an OSError

* pathlibs  glob function doesn't return the correct case (https://bugs.python.org/issue26655). So switching back to  glob.glob()

* removing obsolete imports

* * check if relative filename is in excluded file list
* removed find_excluded_files() method from wheel.py

* added test for excluding files in wheels

* creating an own test data folder, for testing excluding files by pyproject.toml

* use as_posix() to respect windows file path delimiters

Allow the `POETRY_HOME` environment variable to be passed during installation to change the default installation directory of `~/.poetry`:

```
POETRY_HOME=/etc/poetry python get-poetry.py
```

* Fix specification of Python versions for dependencies using double
  pipe (`||`) instead of using an array which leads to confusion (see for
  instance https://github.com/sdispater/poetry/issues/847).

* Fixes #847

Some packages (like `pygame-music-grid`) have unparseable metadata.
This resulted in a ValueError. pip ignores packages like these, so it's reasonable
to do the same in poetry itself and only display the well-formed ones.

Fixes #1345.
Fixes #637.

This change fixes the installation of packages using a url source.
Previously, the installer attempted to install the package using the
name ignoring the source url.
