Misleading imagemagick detection

[shazz]

Hello,

convert.exe is a Windows tool so even if not installed

@windows_only which_cmd = "where"
_, p = readsfrom($which_cmd convert)
wait(p)
if !success(p)
warn("ImageMagick utilities not found. Install for more file format support.")
else
have_imagemagick = true
end

returns true

Ah, that's quite unfortunate.

Hopefully soon we will switch over to the io branch, which will do its ImageMagick detection quite differently. If you're interested, it should be much faster (see #24 (comment)), so feel free to give it a try.
