Issue 6748: Unable to download ZIP (and many other filetypes) files attached to emails

Issue: http://code.google.com/p/cyanogenmod/issues/detail?id=6748

This change allow the user to select which extensions of the UNACCEPTABLE_ATTACHMENT_EXTENSIONS
defined by AOSP should allow/disallow from attachment download.
A new General->Security setting was added with a multi select list preference with
all the extensions. By default all the extensions will be marked as blocked.

Patchset 3: Rename disallowed to blocked. Cleanup.

Add action buttons to new email notifications

Another new feature from Slim!

Works similar to Gmail in that single messages have action buttons.
Each action can be toggled on/off, allowing you to revert back to stock functionality.
