Remove coordinate system conversion and detect xyz separator characters

Coordinates now need to be supplied in the same coordinate system as the XYZ files, which is less convenient but has less limit for the kinds of datasets that can be used.
XYZ files with spaces and commas as separators are now supported.

Compatibility with the latest versions of Blender and Meshlab

This release slightly modifies the scripts so that they work with the latest version of Blender and Meshlab.
The readme file now contains notes about the version of each software that this project was tested with.

Version 1.1 with a 64 bit build

Build the application as 64 bit so that it can allocate more memory. This prevents an OutOfMemoryException when trying to create large models.
Also contains some improvements to memory usage and error handling.
