It's been a good run, but keeping it running and updating things with it
is more trouble than it's worth.
In the future, I might create something externally from the satellite
files that actually compares versions and updates/tries to build the
satellites automatically, but it'll be external from this project.
Removed dir_sysroot, changed all dirs to fall directly below dir_prefix (thus removing the need for dir_sysroot, which is only needed in some exotic circumstances anyway), added the ability to build multiple satellites with one command and restructured the way the wrappers work, added configuration file handling in astronautpkg. Updated all satellites accordingly.
