minor corrections to python documentation
Cosmetic rewording to workaround syntax highlighting bug in vim.
html fixes
html doc chapter numbering update since adding Javascript
configure.ac: fix to Javascript configuration

- setting SKIP_JAVASCRIPT assumes that JSCENABLED/JSV8ENABLED
  are empty when jsc/v8 are not available
Fix duplicate entry
Merge pull request #172 from xantares/patch-2

Fix duplicate entry in CPP_TEST_CASES.
configure.ac: print configured languages at end of configuration
Fix segmentation fault in some Javascript examples

- memory allocated with malloc() was then being freed with delete[],
  which is overridden by Javascript libraries (jsc), leading to segfault
- replacing malloc with %new_array seems to work though
Regenerate configured Makefile if Makefile.in or config.status have changed
CCache/Makefile.in: fix to allow out of source tree check/install
Add "make maintainer-clean" to Travis CI build
Allow examples and test-suite to be built out of source tree

- Examples/Makefile.in rules use SRCDIR as the relative source directory

- ./config.status replicates Examples/ source directory tree in build
  directory, and copies each Makefile to build directory, prefixed with
  a header which sets SRCDIR to source directory

- Examples/test-suite/.../Makefile.in set SRCDIR from Autoconf-set srcdir

- Examples/test-suite/errors/Makefile.in needs to filter out source
  directory from SWIG error messages

- Lua: embedded interpreters are passed location of run-time test

- Python: copy run-time scripts to build directory because of 2to3
  conversion; import_packages example copies __init__.py from source
  directory; test-suite sets SCRIPTDIR to location of run-time tests

- Javascript: binding.gyp renamed to binding.gyp.in so that $srcdir
  can be substituted with SRCDIR; removed './' from require() statements
  so that NODE_PATH can be used to point Node.js to build directory
