[Rd] Patch to add Beta binomial distribution. Mentor needed!

[Joan Maspons]

Hello,

I implemented the Beta binomial distribution following the patterns of the
binomial distribution code and inspired by JAGS' code [1]. I have studied
the code carefully but it's my first run in the R internals.

Can somebody review the code and if everything it's ok commit to the
repository?
