Changed all the uuid's. This allows you to have the SWeave bundle and the knitr bundle at the same time and also fixes the ^< shortcut for inserting a code chunk.
Fixed scoping so that the ^< shortcut now works properly. On previous commit, it worked only when using the SWeave bundle (it gave the option to choose from the knitr and SWeave 'insert code chunk' macros).
Changed all sweave mentions to knitr. Still don't know why the menu doesn't show all the commands
