* lots of work on making executables build
- added tests case for wash2hs
- added -i hsSourceDir
- added build dependencies
- since we have to fix dependencies at configure time, I added
  executableDeps to localBuildInfo
  (caused change in format for localBuildInfo)
- added code for actually putting the executables into place.

* libraries

- also added check to make sure there are libraries when building &
  installing the archive and such (hasLibs)
- don't register if hasLibs is false.
