Fix #26: string_methods.cpp does not support ChaiScript 6+ - #29

Automated fix by @leftibot.

What changed

Fix #26: Update to ChaiScript 6.1.0 and fix vector_type API
ChaiScript 6+ changed the vector_type signature from returning a ModulePtr
to taking a Module& parameter and returning void. The ChaiScript constructor
also no longer accepts a ModulePtr for stdlib. Updated bootstrap() to register
the vector_type for std::vectorstd::string directly within the module, and
updated tests to use the new ChaiScript 6+ API. Fixed Catch SIGSTKSZ
compile error on newer glibc where SIGSTKSZ is no longer a constant expression.
