install.sh - Qtah build script

Builds and installs Qtah for a specific version of Qt's API.  Performs an
incremental build, unless clean.sh is run first.  Some environment variables
control this script's operation:

  QTAH_BUILD_JOBS:
    This may be a positive integer, to control how many build jobs are run in
    parallel.  Passed as --jobs to cabal build and used directly by qtah-cpp.

  QTAH_QT_FLAGS:
    This value is passed as --flags to the qtah-cpp and qtah packages, and can
    be used to set the qtX flags (e.g. qt4, qt5).

  QTAH_QT and QT_SELECT and be used to select Qt versions.  See README.md for
  more information.
