Latest small patch for halflife support

>From the CHANGES file:

25/10/2002
  Hydra
  - vfsGetFullPath() can now (optionally) search PK3/WAD files
  - Half-life map loading is now un-borked (my original patch worked
    but some conditional code in the patch was incorrectly applied.
    That, coupled with the missing vfsFileExists and vfsFindFile replacements)
  - A patch to imagehl/lbmlib.cpp/LoadIDSP() was missed out, causing all sprite

    models to be reverse-rendered (due to an inverted alphamask)    
  - Renamed HydraToolz to HydraToolz-HL as it's half-life specific
    changed project files and renamed all appropriate files and directories
    (for the merge, just delete contrib/hydratoolz and apply the diff)
      
  - Comments on previos notes:
  
    - TODO: need to rationalize where the modules are placed and identify HL
specific modules
      (this affects the build system / post build step too)
      imagehl and spritemodel are halflife specific and can be placed in
	either $coreradiantdir/modules or $hlradiantdir/modules
	I've updated the .dsp files so that they are copied to
$coreradiantdir/modules
	spritemodel can actually be used for other engines, not just HL so it
makes sense
	to keep it in $coreradiantdir/modules
      hydratoolz is a half-life specific plugin and must go in
$hlradiantdir/modules as it
	is NOT to be used for any other engines.  I've also updated the "about
text" to 
	reflect this.
