Don't use conda_build

Use the value returned by --output instead. This should solve an error on Appveyor about not being able to import conda_build.

Also, add a new command miniconda_dir that outputs the directory where miniconda lives. Useful on systems like appveyor that have multiple miniconda versions.

VS2010 Fixes

Now that the base Python may be Python 3 (since Appveyor included Miniconda), we need to ensure we correctly
set the build environment for a Python 3 build. This means activating the correct VS2010 environment. This update copies the correct files and sets the correct environment variables for VS2010.

Update for Appveyor

Appveyor now includes miniconda, so we don't need to download it. This also fixes a bug whereby existing installation detection was failing on Windows.

Fix Python 3 Bug

Use urllib.request instead of urllib2 for Python 3

v0.2.3

Adds special behavior for not uploading pure dev tags to binstar.

v0.2.2

With this new release, CondaCI now tries to use versioneer to dynamically find the version strings for a project. If versioneer is not used, it falls back to a method based on git tags that should be PEP440 compliant.

Always grab latest version

CondaCI now gets the latest version of conda rather than a fixed version string.
