separated VIM_EMU replacementdef and included in the top replacementdef.xml

I want to move All VIM_EMU_* replacementdefs in .../Resources/replacementdef.xml.
It allows users to use these replacementdef in their private.xml.

I used "include" in replacementdef.xml.
Although my local test seems fine, but I'm not sure if this is correct way or not.

Could you please check and if it is ok, merge it?
