Merge pull request #562 from mkroehnert/requirejs

Documentation for latest amberc.js features + remove init.js support
Merge remote-tracking branch 'upstream/requirejs' into requirejs-wip
exportMethod:of:on: has of: part omitted
exportClass/Package are now stream writers (have on:)

Less long temporary strings, export should be faster.
exportCategory:on: using composite category object
export package prologue/epilogue has of: part
exportPackage:on: gets a package, not its name
exports' methods have defined structure

all exporting methods have exportStOf: anObject on: aStream,
where anObject is real object (package, class, category, method)

in case of "grouping" methods that just call other methods,
only calling of:on: with same object is allowed, or calling
(self somePartOf: anObject) do: [ :each |
   "same structure, but with each instead of anObject"
].
PluggableExporter, using recipe, exportAll pulled up
*Exporter classes do not inherit from PluggableExporter

They are planned only as sources of recipes
(and repository of worker methods) for PluggableExporter.
Worker methods moved to class-side
recipe moved to class-side
