Fixes a "copy over" bug in input3.c

The copying of one input line token over another was causing a compilation error under Clang. With v2.2 this copying is no longer needed so the line of code in question was simply deleted.

This commit also deletes the HTML and Latex output generated by running Doxygen that got added from the previous update to dev since they don't really belong in a source code repo.
