Missing MFE_ constants in Lua/SOC

"TOUCHLAVA" and "TRACERANGLE" are missing from MOBJEFLAG_LIST in dehacked.c, meaning that the constants MFE_TOUCHLAVA and MFE_TRACERANGLE are not accessible to SOC or Lua. But even worse... the fact that MFE_TOUCHLAVA in particular is missing means all those after it in the list (MFE_PUSHED, MFE_SPRUNG and MFE_APPLYPMOMZ) all have the wrong values as a result. In other words, MFE_PUSHED actually has what should be MFE_TOUCHLAVA's value, MFE_SPRUNG has MFE_PUSHED's value, and MFE_APPLYPMOMZ has MFE_SPRUNG's value. This is bad for obvious reasons and should be fixed asap.
