Rules for emscriptening
Working emscripten example (tas.html)

Refactor non-main() tas.c code into asmif.c.
Add asmif.h ; refactor and simplify example
Example webapp framework
Mend multiple executes ; work on mending node.js
Update emscripten build rules for new examples
Refactoring tsim into multiple files

Start maintaining non-UI-specific code in simif.c and dbg.c to allow
easier swapping of frontends.
Preparing to emscripten tsim properly
Mend missing reference to stdint
Support setting CPP to a pipe-only cpp

Pipe-only cpp interface should understand -I, -D, and -U but nothing
else. This supports a minified version of tinycc's C preprocessor that
is intended for use in an emscriptened environment.
Add submodule for tinypp

tinypp will be used in emscripten-powered web demo.
Starting to build up web UI with emscripten
Mend bad dependencies for tas.bc
Full build procedure for web UI
Labels support in ui/web

Labels were causing failed assembles because tsearch() wasn't found (no
implementation in emscripten's standard library). Implemented tsearch()
in terms of (also custom) lsearch() for ui/web build only.
Properly separated emscripten build in ui/web
Update ignores
Tentative tsim build
Cosmetics
Better example code, cosmetics, description
