initial script to build the local raaz package repository
Makefile rules for building the index
script to generate cabal config file
build rules to compile scripts
reworked and simplified the install rule
raaz-primitive: extra source files used by setup script added
some adjustments to fix cabal sdist problem

- The cabal sdist command is not including the load_test.h file even
  when listed in the includes of the test suites. So we essentially
  copy the headers contents on to the C file.
raaz-primitives: added missing test modules
raaz-cipher: added missing test/benchmark modules
raaz-hash: added missing test modules
raaz-random: added missing test modules
moved modules of raaz-config to raaz-primitives
got rid of the raaz-config package
configuring raaz-primitive before tarballing

- The config.h file in raaz-primitive is generated. So we need
  configure the package before tarballing.
added missing platform cabal file
fixed the raaz-random test
now does not build for platform 2012.2.0.0
Merging in new style travis build

- Now creates a local repo and builds raaz packages from there. This
  removes the need of package tracking using the Makefile

- Platform constraints are now generated directly from the platform
  cabal files.
