Add Heroku support

Move .bowerrc, bower.json, gulpfile.js, package.json
down to root level.
Update paths in .bowerrc, gulpfile.js, Makefile
Add a heroku-postbuild step to package.json which
installs devDependencies and runs the build.
Add step in bin/pre_compile which adds the
requirements_all_ds.txt to requirements.txt to ensure that
cffi is installed. Also removes pymssql as this is
not supported on Heroku.
Add content from rd_ui/.gitignore to .gitignore and
remove rd_ui/.gitignore.
Add section in setup.rst about Heroku deployments.
