- fixed: WIF_STAFF2_KICKBACK did not work anymore because it depended on conditions

that were changed some time ago.
- fixed: The damage inflictor for a rail attack was the shooter, not the puff.
- Fixed: Floor and ceiling huggers may not change their z-velocity when seeking.
- Fixed: UDMF set the secret sector flag before parsing the sector's properties,
  resulting in it always being false.
- Renamed sector's oldspecial variable to secretsector to better reflect its
  only use.
- Fixed: A_BrainSpit stored as the SpawnShot's target the intended BossTarget, 
  not itself contrarily to other projectile spawning functions. 
  A_SpawnFly then used the target for CopyFriendliness, thinking it'll be the 
  BossEye when in fact it wasn't.
- Added Gez's submission for a DEHACKED hack introduced by Boom.
  (using code pointers of the form 'Pointer 0 (x statenumber)'.
- fixed: Attaching 3DMidtex lines by sector tag did not work because lines
  were marked by index in the sector's line list but needed to be marked by
  line index in the global array.
- fixed: On Linux ZDoom was creating a directory called "~.zdoom" for 
  save files because of a missing slash.
- fixed: UDMF was unable to read floating point values in exponential format
  because the C Mode scanner was missing a definition for them.
- fixed: The recent changes for removing pointer aliasing got the end sequence
  info from an incorrect variable. To make this more robust the sequence index
  is now stored as a hexadecimal string to avoid storing binary data in a string.
  Also moved end sequence lookup from f_finale.cpp to the calling code so that
  the proper end sequences can be retrieved for secret exits, too.
