biogem 'convention over configuration'

[pjotrp]

I think biogem should default to the following switches:

--with-bin --rspec --cucumber --with-ext --with-yard

and perhaps more. It is much easier to remove files after generating a biogem, than thinking later: 'Oops, I should have added this switch'. Besides, people can learn from what is generated. Similarly both README.rdoc and README.md can be generated.

It is better to leave the option of having a little more, than a too little. Generated code is harmless.

Typos: --with-ext => --with-ffi and --with-yard => ``--yard`

I'm not sure I agree that this is quite "convention over configuration" in the usual sense, more just "sensible defaults". But that's just me.
