Added many more tests of the pmtools programs
Added tests for remaining pmtools programs
Modified programs and modules to use a fixed value for $VERSION

1) Modified programs and modules to use a fixed value for
   our $VERSION, rather than trying to determine it dynamically.
   This should work better with the CPAN toolchain. This means
   all programs and modules have our $VERSION = '1.50'.
2) Fixed pfcat documentation to always refer to "pfcat".
3) Updated Changes file for this release.
Fixed t/pmload.t regex match for module(s) loaded
Updated TODO
