Drop backported relpath implementation

The client now requires python>=2.6, where the os.path module has a
relpath function.
Create function to return the files under the project directory

Abstract that functionality in a separate function.
Drop import of with statement from future

The client now uses python>=2.6.
Minor: style changes
Use only posix paths in the config file

Convert to/from posix paths from/to native paths whenever
storing/reading values to/from the config file.
Merge branch 'fix_paths_in_windows'
Add support to setup.py to build windows executables, too.
Follow soft links, when discovering the files

Follow the soft links present, so that we can handle cases, where the
actual files are in a separate directory tree than the tx project.
Update links in README and setup.py
Add support for local .transifexrc file
Verify SSL certificate before any request

Use a list of root certificates from Mozilla, which is licensed under
GLv2, too. In any case, [1] allows us to use the file even under MPL.

[1]: http://www.mozilla.org/MPL/2.0/combining-mpl-and-gpl.html

Fixes CVE-2013-2073.
Make cacert.pem work for windows, eggs etc, too

Use pkg_resources to locate data files. Also, when in windows, store the
certificates file in the app's directory.
Fallback to distro-specific files for SSL certs

Rely on the distributions to provide any updates.
Limit the number of wildcards in a SSL cert to two

We shouldn't have more than two in practice.
Merge branch 'ssl'
Drop erroneous file header

Link and license mentioned are wrong.
Bump version to 0.9
Update the MANIFEST with the pem file.
Bump to 0.9.1
fix: include 'type' when set --auto-remote
