[TxMt] Sweave bundle

[Ana Nelson]

I've just added the following command to my Sweave bundle for using  
the command line interface to R rather than the GUI:

M=${TM_SWEAVE_WD:=${TM_DIRECTORY}}
echo -e "setwd('$M')\nSweave('$TM_FILEPATH')" |  
"$TM_BUNDLE_SUPPORT/../../R.tmbundle/Support/tmR.rb"

Note this assumes both R and Sweave bundles are located in the same  
directory. The /../../ is to back up from the Sweave bundle Support  
directory and go into the R bundle Support directory.

Command output should be set to "Show as HTML"

I have only tested this on example-1.Snw
