scons: updated to 3.0.1

RELEASE 3.0.1:
- Jar can take multiple targets, and will make a duplicate jar from the sources \ 
for each target
- Added some warnings in case the Jar builder makes an implicit target
- Added Jar method and changed jar build to be more specific. Jar method will take in
  directories or classes as source. Added more tests to JAR to ensure the jar was
  packaged with the correct compiled class files.
- Added a No result test case to handle bug which seems unrelated to java in the
  swig-dependencies.py test, more info here: \ 
http://scons.tigris.org/issues/show_bug.cgi?id=2907
- Added a travis script to test on ubuntu trusty now that the project is on github
  so that Continuus Integration tests can be run automatically. It tests most \ 
case and considers
  no result a pass as well. Improving this script can install more dependincies \ 
allowing for more
  tests to be run.
- Updated the Jar Builder tool in Tool/__init__.py so that is doesn't force \ 
class files as
  sources, allowing directories to be passed, which was causing test/Java/JAR.py \ 
to fail.
- Fix issue where code in utility routine to_String_for_subst() had code whose \ 
result was never
  properly returned.

- Fixed Variables.GenerateHelpText() to now use the sort parameter. Due to \ 
incorrect 2to3 fixer changes
  8 years ago it was being used as a boolean parameter.  Now you can specify \ 
sort to be a callable, or boolean
  value. (True = normal sort). Manpage also updated.
- Fixed Tool loading logic from exploding sys.path with many \ 
site_scons/site_tools prepended on py3.
- Added additional output with time to process each SConscript file when using \ 
--debug=time.
- Fixed a regression in scons-3.0.0 where "from __future__ import \ 
print_function" was imposed
  on the scope where SConstruct is executed, breaking existing builds using PY 2.7.
- Fix broken subst logic where a string with "$$(abc)" was being \ 
treated as "$(abc) and the
  logic for removing the signature escapes was then failing because there was no \ 
closing "$)".
  This was introduced by a pull request to allow recursive variable evaluations \ 
to yield a string
  such as "$( $( some stuff $) $)".
- Fix incorrect warning for repeated identical builder calls that use overrides
