Use hub for push alias
Liberate single-letter leader commands
Remove db:test:load from migration aliases
Start spring before starting vim in tmux
Remove tabline from airline

push-to aliases for staging and production
Update default gems

Removed some gems that are going to be app-specific in any event, and
added gems like gem-browse that are not likely to get pulled in by
bundler
Add vim-leaders
Remove vim-projectionist, add vim-run-interactive

vim-projectionist has conflicts with vim-rails when it is loaded after
vim-rails. I don’t want to get into weird overrides with the thoughtbot
configuration, so ditching the plugin for now.

Adding back vim-run-interactive to get access to the <leader>r mapping.
Always force-push current branch to staging

Allows easy use of feature branch for testing on staging.
