Refactor Bundler aliases
Update copyright
Allow functions in a module to be symlinks

Add the '-' flag to the function glob which makes the other flag test
against the target of the symlink, and not the symlink itself.

When using rcm (https://github.com/thoughtbot/rcm), the function files
are symlinked by default, but the current glob excludes them by
targeting normal files (with the '.' flag).

[Fix #523] Ensure zprofile exists before sourcing it
Fix README.md: PATH was moved from .zshenv to .zprofile
[Fix #514] Use /tmp when $TMPDIR is undefined
Don't use sudo if implicitly called by Pacman frontend

Don't rely on alias expansion to handle Pacman because aliases
are not expanded in sudo.
