Update Blob.cs

Update _slice start and end parameters to long to allow larger files. Also added an argument to the Blob dispose method because Moxie was passing one in and reflection couldn't find the appropriate method.
Update XMLHttpRequest.cs

If using the BrowserHTTP client a call to response.Headers throws an exception, so the previous code was causing and catching an exception every time a chunk was uploaded.
Image/XHR, HTML5: Fix pre-webkit Opera doesn't set type property on the XHR blob response.
Allow latedef for functions in jshint.
