bus_future consistency (new TIPID, RSP_ID col, and edit SCENARIO col)

[tk-oleary]

bus_future currently stores TIPID and RSP_ID in the NOTES field. For consistency with highway and rail project coding, bus_future should have separate fields for TIPID and RSP_ID

[tk-oleary]

bus_future now contains SCENARIO_YEAR field, along with SCENARIO. TIPID, RSP_ID, RCP_ID remain to fix
