Optionally use physical address for mapping in ELF segments

[emesare]

Right now we only select physical address for mapping in ELF segments if the signatures is "CGC" however this behavior might apply to more than just those so we should have a setting in "Open with options" to map in the ELF segments with their paddr for users to override. The default should of course should still be vaddr.
