WIP Gemfile now reads from local gem configuration files to set the :github and :branch gem dependencies

@michaelkirk and @gregeng - i know now that :github (vs. :path) is
_required_ by bundler to enforce local branch assertions
adding pry because i saw @michaelkirk use it to great effect the other day
updated server version to 0.9.167.pre1
renamed the xtc-profiles.yml to conform to new briar convention
removed DerviedData cleanup code from xamarin-build.sh - briar will do this for us now
did some refactoring, but this Rakefile is about to lose most of content because the functionality has been migrated to briar
bumped briar version to 0.1.3 in the Gemfile
disabled RubyMine shebang inspection
now ignoring .env files because they should be user specific
reversed the symlink for the Gemfile

the only reason the Gemfile is in features is because the .idea file
lives in features.
