Added the general modules test files

Added the new general module's test file, general_test.go. This replaces the
helpers_test.go file.

There is also a minor defect fix in general.go's StripHTML function.
The correct xhtml tag for a break is <br /> not </br>. I've also removed
the unnecessary spaces before the replacement "\n".

The new test module also reflects this change.
