Normalize line endings

[0u812]

Hi Stanley, this is going to be a huge changeset, but the only change it contains is the line endings. I found a bunch of files with CRLF line endings, and git forced me to change some of them immediately upon cloning. This change will allow other people to clone the repo without getting bitten by the line endings and keep our forks in sync.

Here are the CRLF files before the change:

$ cd sbml2matlab && find . -not -type d -exec file "{}" ";" | grep CRLF
./CMakeLists.txt: ASCII text, with CRLF line terminators
./bindings/CMakeLists.txt: ASCII text, with CRLF line terminators
./bindings/python/CMakeLists.txt: ASCII text, with CRLF line terminators
./bindings/python/pydoc-doxygen.i: HTML document, ASCII text, with very long lines, with CRLF line terminators
./bindings/python/doc-converter/Makefile: ASCII text, with CRLF line terminators
./bindings/python/doc-converter/pydoc-doxygen.i: ASCII text, with very long lines, with CRLF line terminators
./bindings/python/doc-converter/out.i: ASCII text, with CRLF line terminators
./bindings/python/local.i: ASCII text, with CRLF line terminators
./bindings/python/pydoc-normal.i: ASCII text, with CRLF line terminators
./bindings/swig/sbml2matlab.i: C source, ASCII text, with CRLF line terminators
./doc/sbml2matlab-mainpage.txt: ASCII text, with very long lines, with CRLF line terminators
./doc/sbml2matlab-license.txt: ASCII text, with very long lines, with CRLF line terminators
./.gitignore: ASCII text, with CRLF line terminators
./.gitattributes: UTF-8 Unicode (with BOM) text, with CRLF line terminators

and here's the output of the CRLF scan after the change:

$ cd sbml2matlab && find . -not -type d -exec file "{}" ";" | grep CRLF
$ # no matches
