* fRiss:
- improved DESCRIPTION
- added REQUIRES
- added BUILD_PREREQUIRES
- made the conditional in BUILD work
- builds on x86, but crashes
* Weather:
- Updated to newer srcGitRev
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used

* this fixes the wrong recipe names introduced by myself in #d525fee
* adjust patch names to match corresponding recipes
* additionally: create 'additional-files' folders as hint to some
ports that do not have a proper recipe yet
