Add -saveSource and -saveSourceOutput flags to the compiler.

When -saveSource is specified, GWT will write out all source
files referred to in a sourcemap. By default the files will be
saved in extras. The -saveSourceOutput flag may be used to save it
somewhere else.

Part of implementing issue 8378.

Removes unnecessary JSNI from DOMImplStandard.

It looks the code is from the time before '==' was working propery for JSOs.

Cleans up all usages of '__listener' and 'isMyListener'

Plus, gets rid of the boilerplate for dispatching events from DOM.

In addition to simplifying the code path, this also fixes two issues.
1. Ensures that all __listener access are multi-module safe.
2. Ensures that isMyListener can be only called from JSNI to prevent inlining.

For most apps no behavior change is expected.

Prevent setValue from accessing unneeded values

Updated widgets that fire ValueChange events to not read values from the
DOM if those values are not needed (the ValueChangeEvent is not actually
fired). This might prevent slow reads of values from the DOM.

Add hook for validating Super Dev Mode's devModeUrl

This commit adds a "devModeUrlWhitelistRegexp" configuration variable
that can be used to limit what URLs Super Dev Mode will try to load
from.  This can be used to help alleviate the risk of XSS issues in
production applications by restricting devModeUrl to likely URLs
(e.g., localhost or *.example.com).
