New version with standalone packages

This new release doesn't add anything significant but fixes a number of issues:

• Radial, circumferential, and longitudinal directions on meshes are calculated correctly
• Strain is calculated properly now
• Track directories will now get a track.ini file which contains a lot more info about the tracked image, enough that the original image doesn't need to be referenced any more when using the track info, so the "source" boxes will get removed from the UI soon. Older tracking directories without this file will cause the project to ask the user to identify which image was tracked to produce that data.
• Cython fixes to get the newer versions to work, through some quirk some ambiguities with *Matrix add/sub/div/mul were working when they shouldn't have
• Deadlock bug with AlgorithmProcess.sync() fixed, this was causes tasks to hang forever in some cases
• Reorganizing code into packages in the correct Pythonic way
• ImageAlignPlugin now called CardiacMotionPlugin
• Numerous minor fixes

This release has 3 files for fully-contained distributables:
