Duke3D: Add a way to disable the hardcoded squish quote
Inside the function
VM_CheckSquished() which is executed only for the CON conditional
ifsquished, there exists a hardcoded call
P_DoQuote(QUOTE_SQUISHED, vm.pPlayer) that is executed anytime the conditional returns true. This particular quote cannot be disabled by compiling using EDUKE32_STANDALONE.
Since there is really no reason for this quote to be hardcoded, and to free up quote slot 10, having this be disabled at least for EDUKE32_STANDALONE might be a good idea.
