Intention to drop Wubi from 13.04 release

It's hard to make an informed decision without knowing the usage stats of
Wubi. If it's quite low then I expect there'd be little impact, but if it's
popular then it's taking a low-risk installation method away from users who
might otherwise not have tried Ubuntu. Does Canonical have any statistics
on this?

Re. the bugs. I had a look at "Wubi fails to detect 12.04.2 and 13.04 AMD64
ISO" and found that the fix
is a one-liner configuration file change (in data/isolist.ini).

The fix for "13.04 installer doesn't create user account" could be to simply remove the
disk-image installs from 13.04. This again is a two line removal from the
same configuration file.

I've patched and tested both 12.04.2 and 13.04 with these changes to
confirm they work.

Re. Windows 8: that may not be solvable right now, but I expect there are
still many more BIOS-based computers out there than UEFI. And the regular
dual boot for UEFI has many problems as well. Wubi could probably be
smarter about checking whether Windows is booting through UEFI and exit
gracefully prior to downloading the ISO/diskimage.
