Add handler to handle dangerous download items

Some download types are dangerous and android doesn't have a handler for this.
As a result, many downloads will fail silently.
This change uses the infobar to warn users about the dangerous download items.
The UI is kept similar to that of the quota permission infobar.
When user hit the ok button, download will proceed.
If user hit cancel or close the infobar, download will be canceled.
