+ Test runner GUI gui_fruit.rb is added.

  To use "gui_fruit.rb", other two ruby scripts
  "rake_base.rb" and "rake_estimate.rb" must be in the same directory.
  Before starting GUI, Fortran compiler setting in "rake_base_db"
  should be edited.

  Works both for single directory projects and multiple directory projects.
  Here multiple directory project means project consist of
  one source directory (contains tested fortran files) and
  one tester directory (contains tester fortran files *_test.f90).
  For example, within fruit distribution tests
    "self_test", "sample_selective", "sample_single_dir",
    "in_3_minutes" and "sample"
  can be run using GUI.
