Source local bash profile before dotfiles.
Source local bash profile before dotfiles.

Source any local bash profile in `.bash_profile_before` prior to
sourcing any of the dotfiles in this project. In the future, I can add
support of `.bash_profile_after` if need be.

No longer sourcing `~/.profile`.
