Set default search type for 16-bit, 32-bit, float, etc. to aligned; move unaligned searches below and designate with (unaligned)

[Souzooka]

As per the title, in the Memory Inspector tool, in most circumstances a user wants to find an aligned 32-bit or 16-bit value instead of an unaligned value. I recommend therefore changing the default behavior of a 32-bit, etc. search to aligned and instead having an unaligned 32-bit search be the alternate, lower-priority option.
