Fixed the wrong raster channel assignment in raster_jun04.map. The X and Y channels needed to be switched.
In both map files, changed the plane assignments of all the raster channels to be 1 instead of 1,2,3,4. This then follows the ENGINE convention.

In raster_jun04.map, reassigned the raster channels into a single plane instead of different planes.
This makes it easier for comparision with the engine.
Modified raster_test.C to analyze run 52947 in the cache directory.
Some minor clean up in the THcRaster.cxx class- removing comments and unused variables.

This works and it makes easier for the mapedit_rasterbcm.pl script to propagate these changes into ENGINE type map files.

  Files with the prefix raster_ are coppies of original *.database,
  and *.param files which now includes changes nessacery for
  decoding raster data. I created seperate files for these because I
  need to merge this code upstream before I can compare the raster
  decoding results with that of the analyzer. For e.g. the map files are
  different from the original map files. So Steve needs to create a perl
  script that can propgate these changes in the map files to the map
  file of the analyzer inorder for me to do the analyzer hcana
  comparision. Once the comparision is done and we are satisifies with
  the results, we will merge the changes with the original files and
  remove the files with the prefix raster_*.

  gbeam.param now included by general.param.  No need to load
  a separate parameter set to test raster/BPM code.

  examples/MAPS/raster_jun04.map adds new detector IDs for the raster
  and BPMs as follows:

Add the following IDs to the misc elements,
BEAM
 RASTER_ID= 18          ADC
 BPM_ID= 19             ADC

In the channel section did the following modification:

Put map files in MAPS subdir.
Define correct map for run 50017 in test.database.
Add a script to display drift chamber hitmaps.
Fix make_cratemap.pl so that it makes an entry in db_cratemap.dat
  for all Fastbus slots.
