Implement a more simple and elegant integration of the R package knitr. Now, lyxknitr.R does not need to move or copy files at all. This also fixes a bug: when /tmp was on a different file system (e.g. encrypted home), lyxknitr.R failed to move files to /tmp because it relied on R's 'file.rename' function, which in turn relied on the rename function in <stdio.h>, which was failing with the EXDEV errno. Patch from Yihui Xie.
