Writes the starting device overview information of all known devices to
the top of the saved details HTML.  This is so that hopefully we don't
need to additionally ask users for their disk layouts via 'fdisk -l',
'parted print' and 'lsblk' when the saved details file is provided.

Also moves the equals separators "==================" from below to
above each operation so the each section is separated.

Bug 639176 - Save partition layout to gparted_details.htm
