Log Message:
-----------
Use binary wrapper executable on all platforms.
The main motivation is to fix issues with paths with spaces on Windows, which apparently is just not doable in a shell script.
This version NOT yet tested on Windows, Windows binary installer will need adjusting, some cleanups to follow.

+- Fixed: Problems starting from paths with spaces in the file name on Windows
+- Added command line option --r-executable for switching between several installations of R
+- Use a binary wrapper, instead of wrapper shell script for startup on all platforms
- Linear regression plugin gains option to save predicted values
- Fixed some compilation problems
- Add basic support to export plots using tikzDevice
