port dojo offline + Gears to 0.9

[alex]

There's some work in the bootstraps of brad's new work that detects Gears and makes it available x-browser (in lieu of the gears init scripts that the gears SDK ships). These need to be ported along with dojo.sql and dojo.off which need to now live in dojox.

[alex]

(In [8892]) adding Google Gears detection support. Refs #3252

[alex]

(In [8893]) initial work in porting dojo.sql from Brad's experimental branch. Also includes working Gears storage provider and refactored dojo.storage now at dojox.storage. Removes seriously janky "singleton and superclass" weirdness from the storage system and fixes myriad style issues in all of these modules. Refs #3252

[alex]

(In [8894]) gotta move this out to the right file location, but for now, just checking in before I mv it. Refs #3252

[alex]

(In [8895]) clobbering catch-all provider file. Refs #3252

[alex]

(In [8896]) working WhatWG provider and updated loader. Refs #3252

[alex]

(In [8902]) ensure that the storage stuff is more-or-less in place. Refs #3252. We should be able to start porting in dojox.off now.

[alex]

(In [8905]) not yet functional, but it's a start. Things seem to require() without syntax errors now. Refs #3252

[alex]

(In [9004]) make offline start working. That we have to call dojox.off.initialize() manually seems rather strange, but when we do, we can at least get incremental checks for online status now. Errors are still not being handled correctly for that, but we're really close to getting it going. Refs #3252

[alex]

(In [9012]) fixing more of the Java-in-JavaScript? cruft that pervades the offline code. Ensuring that the _loadedUrls property of the dojo object actually acts as an array. Refs #3252

[alex]

(In [9013]) c'mon people, you're better than this. The craptastic java-in-javascript has to end. Every byte counts. Refs #3252

[alex]

(In [9014]) updated for style and some API moves. Refs #3252

[alex]

(In [9015]) removing getType(). Use declaredClass instead, it's free. Refs #3252

[Eugene Lazutkin]

(In [9022]) Just to be pedantic --- removing unnecessary checks, which are covered by !message. Refs #3252.
