20150722 - 1536-3 : Simplify, Repeat

+
+ +Night 3 on the 1536 project, decided to make some changes before going full ahead with writing an editor.
+
+(1.) Switched the boot loader to not relocate to zero. +Now leaving the BIOS areas alone, I doubt I'll ever go back to real mode after switching to long mode, +this ends up making the code easier, and provides room for the next change.
+
+(2.) Switched the boot loader to fetch the first 15 tracks instead of just 1 track. +Now have a little over 472KB of source to work with on boot, +which is effectively infinite for this project. +The motivation for this change was the realization that x86-64 assembly source would get big. +Don't want to change this later. 472KB is close to the maximum without checking for things like EBA, or handling non-full-track reads.
+
+(3.) Switched to an easier source model. Lines are now always 64 characters long. +Comments are switch to a single \ which functions like the C // style comment, ignoring the rest of the line. +Since lines are always 64 bytes (cacheline sized and aligned), +the interpreter can quickly skip over comments. +This is a trade in increased source size, for simplification of the editor: +fixed size lines makes everything trivial.
+
+(4.) Making a convention that syntax highlighting with color only has a line of context. +Which translates into don't let things wrap. Easy.
