Consider including DTC removal DLL in LITE installer

Current feedback from DWWA and Aurion Corp suggest this is going to be a difficult scenario to deal with in its current state. As such, we should consider including the DTC removal DLL in the LITE installer so that's it off by default and can be optionally removed/renamed to turn it back on (which will probably never happen). This would mean we should be doing all our testing with transactions turned off.
