Subject: [PATCH] Improved Cheetah type casting for int/float types.

Based on idea by @peterjc in a discussion here - http://dev.list.galaxyproject.org/Geting-integer-value-from-InputValueWrapper-in-plugin-xml-file-td4666971.html. With simple test demonstrating new functionality. Run test with

    ./run_tests.sh -framework -id cheetah_casting
