Subject: Allow flashing of images via the GUI

- Use the Images... button in the lower right of the zip install
  page
- Unify image flashing functions between restore and image flash
- boot and recovery partitions are flashable by default
- use fstab flag flashimg=1 or 0 to override defaults
- file system partitions are currently not flashable
