build: initial cut of smaller-icu. Use a shell script to build normal ICU.
build: ignore deps/icu
doc: document --with-generic-icu option (experimental)
doc: actually preview the MD before committing.
build: reduce ICU code size a bit more
build: allow CORES to be an environment variable
build: further reduce ICU size, add documentation of special branch-in-progress
build: first cut at allowing v8 to build w/o brkiter (for space)
build: a little more trimming. English only clocks in at 19M.
build: more space reductions, beginning of configuration of icu data dir

(v8) save 1M by making brkitr optional. https://code.google.com/p/v8/issues/detail?id=3345
Better passing of config opts to .gyp
--icu-data-dir= arg added, may not work yet
(v8) InitializeICUDirectory() function to support above  https://code.google.com/p/v8/issues/detail?id=3344
