freetdm: removed ftmod_sangoma_boost, testboost, testsangomaboost, ftmod_sangoma_isdn and ftmod_r2 from default msvc 2008 build

add uuid_fileman <uuid> <cmd>:<val> <-- same vals as the callbacks in js and lua to control the currently playing file of a channel from the cli or ESL (for the people who were ignoring me on the conference call so I decided to implement it instead of try to explain it )
