Move Cross-compiled core from B390 to B350

and renamed it "Core words". Also, reworded the presentation.

+Core words
+
+This section contains arch-independent core words of Collapse
+OS. Those words are written in a way that make them entirely
+cross-compilable (see B260). When building Collapse OS, these
+words come right after the boot binary (B280).
+
+Because this unit is designed to be cross-compiled, things are
+a little weird. It is compiling in the context of a full
+Forth interpreter with all bells and whistles (and z80
+assembler), but it has to obey strict rules:
+
+1. Although it cannot compile a word that isn't defined yet,
+   it can still execute an immediate from the host system.
+
+                                                        (cont.)

+2. Immediate words that have been cross compiled *cannot* be
+   used. Only immediates from the host system can be used.
+3. If an immediate word compiles words, it can only be words
+   that are part of the stable ABI.
+
+All of this is because when cross compiling, all atom ref-
+erences are offsetted to the target system and are thus
+unusable directly. For the same reason, any reference to a word
