Linedef type 4 now works as follows.
* Frontside x offset is dash speed.
* Effect 4 flag doesn't center the player. (same as before)
* Effect 5 flag sends them off in rolling frames. (as a result there is only one speed pad sector type now, not two)
* Frontside upper texture is sound to play on launch, defaults to sfx_spdpad when not given
Linedef type 14 (Bustable block parameter)
* Applied to one of the linedefs of any FOF's control sector
* Concatenation of frontside textures is MT_ object type to spawn, defaults to MT_ROCKCRUMBLE1 if not present
* Sound played when being busted is object type's activesound
* Frontside x offset is spacing (in fracunits) of spawned particles, defaults to 32<<FRACBITS
* Frontside y offset is the fuse of spawned particles in tics, defaults to 3*TICRATE, if set to -1 assume infinite lifetime
* Effect 1/Slope Skew flag makes particles fly out
Linedef type 250 (Mario Block):
* No Climb flag turns it into a brick block (busts when hit from the bottom, player hits their head/fist/whatever, no more upwards momentum)
BACKPORT: removal of music slots
Relevant commits cherry-picked. Basically everything except the internal music track name switches.
See merge request !43
Use whatever names you want for your music. So long as you prefix the lumps with O_ or D_, it doesn't matter anymore.
DISCLAIMER: Linedef type 413 (change music) and Lua scripting is not tested.
