Add support for prioritized loading of bundles

An application may now put "bundle" and "shard" properties in its
"package.json" to designate priority order for a sequence of bundles to
preload and the number of parallel connections to harness.  The "bundle"
property must be an array, where each element corresponds to a step in the
loading process.  Each element may be a string or array of strings, and each
string must be a module identifier.  Each step of the preloading phase will
contain these modules and their transitive dependencies, excluding any modules
that were loaded in a previous phase.  The "shard" count is the number of
parallel requests to use within each phase.  The bundle for each phase will be
divided into up to as many shards to load in parallel.

Added a warning not to use the "root" property of a template module’s exports,
favoring instead the "directory" property.  The "root" property accidentally
exposed a regular expression match object instead of a string.  "directory"
matches the terminology used by the "module" object provided by "require".

Promise: add support for .end(callback, errback) for transitioning out of
promise-passing-style to continuation-passing-style.

Revised the bootstrapping code in "montage.js" so that it guarantees that
bindings support has been set up before the application initializes.

Renamed "require.getModule" to "require.getModuleDescriptor".
"require.getModule" exists but is deprecated.
Fix non-bundled optimized applications

They were previously not loading from script-injection as they were
supposed to.

New Mfiddle

- The main premise is building a component instead of a template (it still works as the previous one if there's no owner in the serialization)
- Faster running the code because the iframe is initialized only once, consequent loads are injected.
- Has a logger that shows console.logs from the running code.
