change isSafari to isWebkit to support Chrome

[James Burke]

Now that there is dojo.isWebKit, consider if it is better to use for these areas:

• _base/event.js
• _base/html.js
• _base/lang.js
• _base/query.js
• _firebug/firebug.js
• back.js
• dnd/autoscroll.js
• dnd/Manager.js
• dnd/Mover.js
• io/iframe.js

(In [16065]) Refs #7845, scrubbing dojo.isSafari use in Core, using isWebKit where appropriate. Have not done dojo.dnd internals though, and dojo._firebug had some isSafari references too, but not sure those need to change. \!strict

(In [16069]) revert isFunction() check for isWebKit. Unit test added in [15738]. Refs #7845

[James Burke]

Core has been scrubbed, closing this bug out. Cannot speak to dojox modules, but that works should be handled by individual tickets by the module owners.
