New package: stfl-0.23

I'm still not sure how packages are properly split.  I am also not 100% sure what vmove ends up doing, I assume it moves libs from the package to the system. 

I tested compiling/running a program against stfl.  Adding the devel package stops me from being able to compile with just the base package installed.  I have to assume this is xbps magic considering I tested this without "pkg_install()" in the template and everything worked as it should.

Again to clarify, I do not know why I should bother with vmove, or pkg_install considering everything works as it should without it.  In either case, I can build and run newsbeuter, which I will also package once stfl is properly packaged.
