bintray "package" should be name not full_name

Based on how it's used to construct URLs, the bintray "package" should
be the formula name not the formula full_name. For core formulae, there
is no difference, but that's not the case in other taps.

See https://github.com/Homebrew/homebrew-gui/pull/10

Closes #301.
