Standalone SWI-Prolog
Prepare static version of SWI-Prolog that should be distributed as a standalone library with the Loki. It should be copy-pasted to the selected directory and that's all (nothing is needed to install, it stays in the directory that is available by the simple server user, not the administrator).
Main idea: compile SWI-Prologa sources with the old GLIBC version + statically link libraries + remove obsolete swi-prolog modules to make it lightweight -> as a result we have 32bit and 64bit executables that we can redistribute with Loki
Update 14.09.2017: static swipl was created. Now Loki should be adjusted to use it.
