Remove trailing slash from custom scripts path
Remove trailing slash from custom scripts path

Homebrew recommends not having a trailing slash.
Also, no other path in /Users/ayushgoel/.rvm/gems/ruby-2.1.3/bin:/Users/ayushgoel/.rvm/gems/ruby-2.1.3@global/bin:/Users/ayushgoel/.rvm/rubies/ruby-2.1.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/ayushgoel/.rvm/bin:~/iTalkto/dotfiles/custom-scripts/ has a trailing slash, so
removed it.
