Erster Commit: nativer Linux-Port aus macOS-Bytecode

Läuft die Voice Acoustic VA-Remotecontrol (AllDSP AllControl) nativ unter Linux
auf echtem wxGTK 3.0 — ohne Wine und ohne dekompilierten App-Code. Ausgeführt wird
das unveränderte Python-2.7-Bytecode aus dem macOS-.app; C-Extensions (wxGTK/numpy/
scipy/PortAudio) kommen nativ aus Debian stretch.

Enthält: va/ (Original-.pyc + pure-Python-Libs + Assets + launch.py mit den drei
Linux-Fixes), Dockerfile/run.sh/entrypoint.sh, reference/ (dekompilierter Quellcode
zum Debuggen) und README/STATUS. img.cache (378 MB, regenerierbar) ist per
.gitignore ausgeschlossen.

+"""
+A few rough Python equivalents of PHP internal functions (=lazy port).
+
+NOTE:
+1) PHP "array" object is mostly similar to a Python "dictionary", but some
+times a "list" (or "array": see Protection.py) may be required!
+
+2) PHP "isset()" tests often wether an array has given key, or a variable
+is defined in global/local space;
+
+3) PHP string functions have often different return values from Python (see below);
+
+4) "for (x; a <[=]b; y)" loops become "for i in range(a,b[+1]):" in Python;
+
+5) PHP emits automatically floats quotients when needed, Python don't: so add a
+".0" to divisors when PDF expects decimal numbers.
+
+Actually, all FPDF tutorials (even from ported modules) work fine, but bugs
+or incompatibilities might be hidden somewhere: so, USE IT AT YOUR OWN RISK!
