Switched listed options to display foad1 instead of foad option, this
is because foad no longer appears to be correctly invoking
fuck.foad1() when foad is set as the fuck type.  Hopefully will be
able to solve this later and restore "foad -f foad" but since there
are multiple options which include numbers now it is less of a
concern.
Converted readme from markdown to reStructuredText to be consistent with the docs.
Removed markdown version of README in favour of reStructuredText.
