Add-on that allows conversion stl->stp and import of .stp into Alibre Version 2.2

This version includes code contributed by Simon Baxter @simonb65. The changes are largely aimed at improving the import and conversion of STL files generated from Blender but also change some aspects of the STP files generated. Testing against a number of different STL files has not revealed any downsides. If users do find files that will not convert or convert with errors, please let me know.
Additional changes are mostly housekeeping; removing unused imports and correcting formatting.

The uninstaller should be found in the C:\Program Files\AlibreImportStlAsStep directory

Rebuilt stltostp from sources for release deployment. Previously stltostp was a debug version.
Added runtime libraries to fix error on systems where these may not be present.
