[GSAS-II] New self-installers for GSAS-II

[Toby, Brian H.]

I have created new self-installer files for GSAS-II, they are named g2conda-0.1.2… and are found here: https://anl.box.com/v/GSASII. Instructions that reference these installers are found here:

Windows: https://subversion.xray.aps.anl.gov/trac/pyGSAS/wiki/SingleStepWindowsNew
Mac: https://subversion.xray.aps.anl.gov/trac/pyGSAS/wiki/MacSingleStepInstaller
Linux: https://subversion.xray.aps.anl.gov/trac/pyGSAS/wiki/LinuxSingleStepInstaller (note this is new)

These files address the problem previously commented upon where the hdf5 packages were not being installed with Python, which produces a warning message from the HDF5 importer. There was also a problem with matplotlib on Macs with a Retina display. Note that you do not need to do a fresh install to fix these problems, if you have GSAS-II installed with anaconda or the recent miniconda-based Python installation, you can fix these problems using commands something like (path ~/g2conda/bin/ may be different for you):

	~/g2conda/bin/conda install h5py hdf5

and for macs, also do this:

	~/g2conda/bin/conda install matplotlib libpng
