All I did was pasting the following lines, with the correct shipname into the bp-3612-shp.tbm file (in front of the #END token), for each ship you want to give glide.
You can get the correct internal shipnames for each mod out of the ships table file.... in case of BP2 that is bp2-shp.tbm.
Though I can't really tell wether it's that easy for other mods, since I only tried it for BP1 and 2. The bp-velindc-sct.tbm is only there to enable the velocity indicator that helps you a bit in seeing which direction your ship currently flies.
