Fix scripts, add readmes to package

This commits do three things:
  * add me to AUTHORS file :-)
  * include all readme files (COMMENTARY, BUGS, TODO etc.) in the package as ```extra-source-files```
  * clean up scripts:
      * ```ghci``` renamed to ```ghci.sh```, moved to ```scripts``` and updated. Works with GHC 7.6.2, I experienced problems with GHC 7.4.1
      * ```build``` script removed - we have ```cabal build```
      * ```GenHaddock.hs``` removed - we have ```cabal haddock```
      * ```timein.hs``` removed - it was a broken hack that couldn't be fixed and it wasn't used anyway
      * ```oneline.rc``` moved to ```scripts``` subdirectory
      * ```oneline2.rc``` removed since it's basically a copy of ```oneline.rc```
