Uses zsh arrays and globbing to find .xcworkspace and .xcodeproj files.

Also adds the lodash URL (which was missing) and uses https on those websites
that support it.

Per warning message.

Remove redundant semicolon to make tab() works better in ITerm 2.

Gaaah.

This plugin was designed so that if there is any failure, it will simply call itself recursively. Which means that if you were working offline, if `quote` was called in your `.zshrc`, you would be unable to open a new terminal session.

I fixed this by allowing the plugin to output nothing if a quote could not be fetched.

I use that command a lot of times, and there's no shortcut for that.
Now it does :)

with symfony 2.7 command group titles are listed as commands. this commit prevents it.

Some refactoring.

This commit uses the `git status --porcelain -b` format to gather the
number of ahead and behind commits related to the remote branch.

This version uses `git status --porcelain` instead of making
multiple calls to `git status`.

This fixes the typographic error that always assigned an undefined
array to `$names`, which made `$list_size` = 0 and triggered a
divide by zero error on the next line.

Fix #1579.

This prevents the previous behavior that exitted the zsh session
even if fbterm didn't start correctly.
