Removed support for Gears and Browserplus

- Removed Gears and Browserplus support
Google Gears losted support at Nov./11
(http://gearsblog.blogspot.com.br/2011/03/stopping-gears.html) and
Browserplus is a discontinued product
(http://developer.yahoo.com/browserplus/), with GitHub repo with last
update at 2 years ago. There is no sense to keep mantaining support for
these platforms. They can be a risk to the security and browser
stability. plupload 2 does not have support for these platforms.
- Updated `examples` and `test` dirs
-- Updated jQuery to 1.9.1
-- Updated qUnit to 1.11.0
-- Updated jQuery UI to 1.10.1
-- Removed `shim.html` example file (it does not have container attr
set, return `container is not an object` at debug. There is no sense to
mantain it.
-- Updated plupload links at `api.html` and `multipart.html`
- Fixed: `build.vbs` fails to open with Error Syntax.
